- What is frequency ? We see what is Hertz or Hz. What is an electromagnetic wave ? Amplitude , Frequency and wavelength of a wave.
Frequency is the number of waves or events happening in a second.
Everything is dependent on frequency , The Mains Power , the sound and Electronics depend on frequency.We hope you understand how important is frequency. Light, Sound, Electricity depend on frequency. Everything changes if the frequency is changed. We humans measure events with the help of frequency with the unit of Hertz or in short Hz. Named by the scientist Heinrich Hertz. Red, green, and Blue Light are electromagnetic waves.
We count how many of these waves travel through a single point in a second. Lightwave disturbs stability of space to perform work using a positive displacement and negative displacement.
Less number of red light waves traveling in a second and more number of blue light waves are traveling in a second. If 1 wave is traveling in a second then the frequency is equal to 1 Hz. Sound waves are changes in air pressure. humans listen to the frequency at 20 to 20khz.
Mains electricity is 50 Hz or 60 Hz depending on the country. Mains electricity is a single-phase supply which comes to your house. When we apply 3 phase power supply to an ac induction motor and we can change its speed with the help of changing frequency .Videos by Pexel.
We at Anand Systems Engineering manufacture Radio remote controls for industrial cranes and we use 2.4Ghz Frequency to communicate between the transmitter and receiver.

Thanks 🙏
You seem like such a nice person thank you for your educational content my dear friend. Many Blessings for your life my friend.
Good video. I watch it frequently.
I absolutely LOVE the way you explained this! I came to learn more about Hz, however, I received a much deeper understanding with well placed animations and simple language.
This is the video I've been looking for hours today!
Your comment made my day .

This was clearly presented and extremely helpful to me. Thank you.
Thanks a lot for your helpful feedback .
Thank you so much I was seeking this information for a long time.
You are welcome , thanks for watching
You explain ”hard to understand“ concepts easily, however I think it really is down to how they are explained which makes them hard to understand. Thank you for making this Information accessible:)
Finally I understood the basic of frequency. Well explained with many interesting facts..
Thank you for your support.
They way you explained very good, I Subscribed your channel, good to watch your videos, Keep posting
Good stuff. Keep up the good work. Thanks
Thanks for watching
Great explanation! I remember now! Thanks for sharing this jewel; wonderful! I 👏👏👏👍✌
thank you very much sir.
Very well explained
I didn’t know all this knowledge about frequency before thanks a lot

Welcome 🙏
Nice 👍
Thank you very much sir, you solved my one of biggest problem
Helpful👍really good
Thanks a lot !
Very clear explanation u r dedicated to work very nice video
So nice of you
amazing 🎉
Great explanation 👏👏 Thanks!
Thanks
Valuable information sir ... thank you ...
Thanks Alex
Finally understand the basic concept of frequency
Thanks a lot for your positive feedback .
Thanks !!
Such a good vedio
VERY helpful. Thank u
You're welcome!
Thank you..lovely explanation. So when we say low voltage, is it really the voltage or this frequency getting reduced?
Bhai,demotivate hokar channel band mat karna,u r a good teacher kam log samjate hai aise ache se, y not u try some series course creation like ACS etc
Thanks bro
No need to louder your voice sir it's enough, I think it's just the way you talk. And the subtitle is a big help. But anyway, this video really helps me I wonder if you can share us about acoustic too. Thank you!
Thanks for your positive feedback but I don’t have much knowledge in acoustics engineering.
Very well explained.
Thanks 🙏
are frequency hertz videos on youtube accurate? are the videos emmiting accurate frequencies as described in the title?
excellent!
Thanks !
I really like your content very educational. I hope you improve your accent for international viewers. Thanks.
Problem is , I never really thought that I had an accent , and I don’t even know how to improve it
Thank you for your video. I have a question. when it comes to energy, high frequency is bigger than low frequency? Thanks again!
As frequency increases so does energy , radio waves have least energy, X-rays and gamma rays have the most energy, gamma rays have 10 to power 20 times more energy than radio waves.
Hello sir, i have a question..
in house mains there are 2 terminals
Phase and neutral right, for any electronic device circuit completion is needed to work,
That means current flow through phase and go inside device and come through neutral line,
But i use a tester to check voltage in neutral pin when table fan is running, but it shows no voltage, why?
And if one cycle have both negative and positive current then electronics work in negative also??
Good Day Sir, what it a technical different between 50 Hz Generator(in common generator) and 400 Hz Generator(in aircraft gasturbine) ?
thank you
Welcome
So does this explain why many radio control systems feature a red light b/c it has the fastest frequency or is that just to make sure it’s on?
So how do you generate and control frequencies? Can frequencies be sent through a computer to another person?
blew my mind
NICE EXPLAINATION SIR 👍👍
Thanks 🙏
Thank You Anand Sir 😊
Good Explanation 👍👍
Btw, My name is rohit , company name is anand systems Enginnering
@@anandsystemsengineering9142 hmm
Very good teaching sir 👏👏😊
Thanks a lot bro 😎
We live in the 21th century, I wish illustrations were in 3d already. 2d is still confusing. We have the technology.
5:40, 220 V is the rms voltage . In actual case amplitude will goes up to 440V or 400V
hey could you clarify something please: you explained the meaning of hertz.. but i felt there is a gap from understanding hertz to understanding a Terahertz(jumping kilo, giga etc) and i just googled Terahertz and they say its another type of wave which hasnt been utlized,... but then how do we have the blue light.. ? im so confused..
It has been utilised , studied , read about and analysed .
Can You please Correlate This with tetanizing frequency= 1/contraction in Hertz?
Excellent video, I am a warehouse worker. To be paid at a top rate we need to move fast. There is no practical way to accurately measure progress to 100% electronically or manually. Would a certain hz frequency or a variable mhz frequency be possible on a smartphone i could use to help me move more? Thank you much in advance for a potential for a way to potential success. Or if not, i still thank you.
Hi, would just like to know. when counting the number of frequency using a diagram, do we only count one complete wave or cycle which is equal to 360 degrees? Have seen some people counting the incomplete cycle like for example if wave is made up of 3 complete cycles and an incomplete cycle say just a trough or a crest, they refer to them as 3.5 cycles, which for me seems not appropriate given that frequency refers to the number of cycles completed per second. Hopefully would be able to get your thought on this. Thanks!
We have to measure from start to finish , then only the concept of frequency arises , as the definition of frequency is “how many times a complete action has happened in 1 second” . 3.5 cycles is not the correct way of thinking in terms of frequency unless 3.5 cycles leads to completion of 1 action from start to finish .
@@anandsystemsengineering9142 thanks. But just to make things clear using a visual as an example, in this video where you presented the low pitch sound, if we are to find the wave frequency of the diagram you've shown, would it be 1 hz or 1.5 hz?
Your 1000th like
👍👍👍
I was looking just for this explanation. Everyone talks about frequency but in mathematical terms. But it's important to understand why exactly we need to study, why is it so important. Thanks for the video😊
Glad it was helpful!
432hz or 440hz? What do you prefer?
what exactly are the changes that high frequency or low frequency do to the air?
Radio waves change the energy at a particular point in space , radio waves don’t require any medium such as air or water to travel , sound waves change the pressure of air as shown in the video
Should we block our eyes from hearing these high frequencies? I see many videos online and red light therapy pads using noglier requenciees that are put close to the ear. Myfriend told me she had a light therapy pad near her face and her ear was irritated for a day or two.
May be , I am not sure
If yours eyes were suited you could see sound as they are electromagnetic wave
Parts of Canada have a different electrical system.
Please reply how can I make a rf transmitter and receiver
To make a very good transmitter and receiver it will take almost 2 years along with a good team of enginners .
What about the difference between alternating current of electricity and direct current of electricity? Your explanation of frequency suggests to me that direct current does not have a frequency. Is that correct?
Yeah , direct current doesn’t have any frequency .
explained very well sir ..thank you ( please increase the sound volume ... it is quiet low ).
Surely next time
What will happen to the rotation of 50 hz induction motor if you plugged it in 60 hz power supply? What will happen to the motor?
Motor will run faster than 50hz supply and wear out quicker as the motor assembly is not rated for 60hz .
Make more conceptual viedios like this for neet students......by visualising.....and the explanation concepts of neet
U have a great future ahead😊😊👍
Okay sure , thanks for the feedback and positive compliments
Sir what is the physical formula to calculate the frequency
1 Evet per second =1 hz
Sit in the middle of frame looks more professional
Why am i commenting this on a random channel I found at 4am
I have one question. Intensity of light is depend upon the frequency?
Intensity & frequency of light are two different parameters unrelated to each other .
You try to give the video more brightness it will be great if you do
Okay sure
How is the frequency 60hz sound changed to electricity?
Sound is not changed to electricity
Why do we can't see other electromagnetic waves just like we see visible waves?
Because our ancestors adapted to see and run from lions which are only visible in the visible spectrum
If cycles per second and hertz are the same thing, then i say mr hertz discovered nothing and i prefer cycles per second due to the mental imagery it creates vs some blokes surname
NO, I never wondered.
Haha
u said magnet wave have 3 colors...so from where do we get other colors from....?
Think of colours as spectrum instead , and All colours are a combination of Red Yellow Blue , that is how computer screens & colour printers work.
@@anandsystemsengineering9142 ==bro i was talking about magnetic wave....related to the nature and its creation of different colors.....computer and printer i know
Magnetic waves don’t have different colours, when they hit the eye , your brain shows you the colours to differentiate the magnetic waves in the visible spectrum , magnetic waves don’t have colours they are just waves travelling at different frequencies .
@@anandsystemsengineering9142 ....so ....it is aur eyes and brain .....who is inspection and then finalising .....the colors according to the inn receiving length of white colored waves ....??
Still more examples of low and high frequencies in nature will be better.
ok thanks for your feedback
I don't think because of the frequency difference we hear different from different sources, the main reason is timber
😂
you look like sunther pichai
5:46 voltage goes from 220ROOT(2) value as 220 is not the peak value..... 220 volt is the rms value
Yes that’s true, goes to 320 volts peak to peak but that would have confused the viewers. But you are definitely correct.
Thanku
Welcome 🙏
