Unfortunately this video continues to give the false impression that an electromagnetic wave actually constantly goes up and down, up and down, up and down as it travels forward through space. In actuality, the sine wave shape is just a graphical representation of the intensity of the electric and magnetic fields of the wave as it travels through space.
@@ultrameticulous There is a pretty good video on UA-cam called “What is an electromagnetic wave?” as part of the “Physics Made Easy” series of videos. It doesn’t have anything to say specifically about amplitude or frequency modulation, but it gives a good introduction to how the sine wave shape is used to represent the intensity and direction of the electric and magnetic fields. There are many other videos on this subject of course on UA-cam of varying quality and you can always use one of the search engines as well. Hope this helps.
i don't think so. Sound waves are depicted as 'Sine curves' and 'Transverse' in most books with amplitude showing the intensity of loudness. I don't think that undermines the fact that they are longitudinal and they propagate parallel to their motion as its mostly made clear. The subsequent diagrams after the base understanding is to bring the idea closer to the mind of the learner. Its much easier to visualize frequency and wavelength of any 'wave' using a sine curve representation, otherwise, the video didn't even mention the details you're saying...
@@SttmpJohnson idk why UA-cam didn't display your comment. I had to click your account to see it. I understand the concepts. I was referring to what you said, looking for a true visual depiction versus a graphical representation. I actually stumbled on one shortly after asking you. "How does an antenna work - ict #4"
I didn’t do any research but I always knew it doesn’t make sense for a wave to move up and down.. I really need more info on this, could you please recommend me a video or article to explain what is actually happening??
Sending/Receiving txt and crystal clear videos through the air just amazes me. The explanation is one of the better ones, so I thank you.... but they still travel through thin air, YT and the internet, all right through the air.. it's not possible
We can only see a very small portion of it, between 700 (“red”) and 400 (“violet”) nanometers and when all are perceived at once we call it “white”. Beyond violet there’s UV, bluetooth/wifi/TV/cellular signals and cosmic radiation, and beyond red there’s IR heat signatures, radar and radio signals. Hearing is how we make sense of vibration waves, and vision is how we make sense of radiation waves.
Still doesn't help understand frequency modulation. How does an FM receiver tune into one frequency at a time, yet the modulation works (and the information exchanged) through the frequency modulating (changing)?
interesting i think we need to re write p2p torrent protocol , lol for EM waves , imagine sending a movie via EM waves without internet connection to ur friend , lol piracy it next level
The voice sounds wrong. Fake or just read weirdly. Some of it was interesting, though. This seems to be aiming to be a very professional video, but I don't think it's very professional that this video has ads before and after. But I acknowledge that I don't know how to turn ads off either.

Great video. The bit about phases really cleared up a mental block I had.
among many grungy videos, this one is great...clear...perfect
i looked up so many terribly explained videos until i got to this perfect and concise one. thanks!
Great video on the topic, plus the animations really help visualize these topics

Good info. Do you have a recommendation for a video which accurately visually depicts the AM/FM electromagnetic field?...waves?

Nice, easily understandable and adding to knowledge without leaving too much out. thank you for the nice video.
I was just reading about this but the animations were key to understand it, many thanks
UA-cam algorithm is doing its job very well.
I don't think so 😕
That's a good video; simple and clear! thanks!
easy, clear, concrete, just as it must always be. Congratulations
Very well done. Adding this to my video collection for new hams! Thanks.
awesome video, just what I was searching for!
Damn this was so very well done.
Wow I'm really impressed with the effort of simplified concept and beautiful animation
Very underrated video. Thank you so much!
excellent explanation!!!
Thank you, I learned something new today. Small steps every day in search of knowledge.

thank you thousand times for this informative video .
Good video, but the music is too loud and distracting.
No it's not
No it's not
@@SubSilenceYeah it is
Just turn the volume down
I wish i could comprehend a little bit what the guy explained.

“One wave per second” = 1 Hz 😊 0:40
Great video
We're glad to hear it was helpful, Pious! -Scott

More video sir pz on digital communication and wave theory ❤❤🎉🎉🙏🙏🙏💝💝
This was great, but turning the music down would have made it even better.
I liked the video before watching. What technology did you use?
Thanks you such this video
enlightening
Amazing.
I’m pretty sure modern day modems use quadrature amplitude modulation. That’s also what LTE and 5G use.
Music is too loud
Please tune to 370 Hz to cancel out the music.
Excellent video for HAM Radio Technical License (the 1st license we get)
This movie made it all clear! Thank you!!
Love this
Anyone knows this voice owned person name
Well explained sir!!
Great video always underrated.
good explanation dude
#Analog-modulation … 1:25
What an amazing video, too much information zipped together. Well modulated.
This great video made for some easy learning! I wish this was how science was taught back in school =(
I like the part where you talked about electromagnetic waves💀💀
I just learned so much👍🏻🇺🇸
best!
Animations are top notch. However, the narration was off topic and background music was too loud
Just depends what is modulated on to them.
Gorgeius
As a kid I thought AM and FM were adult media and family media.
Amplitude is measure of intensity.

Annoying meaningsless music

The background "music" is distracting, drawing attention away from what's trying to be conveyed.
The voice sounds wrong. Fake or just read weirdly.

Bad corporate music.
I wish this is how I was taught in college🥲
Great video
