You are literally the reason why I am falling in love with physics. Never have I ever found physics so much easier to follow than whenever you explain it. As someone who lowkey has the attention span of a goldfish, I sit through some of your longer (2+ hours) videos and still thoroughly enjoy it.
13:41 A standing wave has 5 loops. How many nodes and antinodes are present? 14:46 The fundamental frequency of a certain standing wave is 175 Hz. Calculate the first 4 harmonics. 16:12 The 7th Harmonic of a standing wave is 280 Hz. What is the frequency of the 4th and 9th Harmonic? 17:35 A 2 meter string produces a standing wave with 3 loops. a) What is the standing wavelength? 18:56 b) What is the frequency if the speed of the wave is 45 m/s? 20:00 c) What is the wavelength and speed of the first harmonic? 22:37 The wavelength of a standing wave with one loop is 12 meters. Find the wavelength of the first five harmonics. 23:38 The wavelength of 5th harmonic is 1.8 meters.

What is the speed of the wave?
I love this dude. he's sounds slightly gangster, and fully genius at the same time. sounds like a New Yorker who made it out the hood because he smart af. Props
Thank you very much, I am from Papua New guinea and it is my first time watching your videos and I got to confess that you are the best in the world. I can't think of any words to describe how good you are at this. I just wish to see you in person and be your apprentice forever. Thank you again and God bless.
I'm going to second all the positive comments down there. Thank you. If the online platform Mastering Physics by Pearson has me hating physics, your tutorials have the complete opposite effect. Thanks again. Great videos.
Your videos are always the best, understandable and satisfying. You covered everything on my textbook for this section. Thank you so much. I will share 25% of my 1st salary with you after graduating. Hopefully our creator will grant you more years to live.
4:45 Note that: L=nλn/2 i.e. λn=2l/n(1). v=λf i.e. λ=v/f(2). From equations 1 and 2, v/f=2l/n i.e. f=nv/2l. When n=1, the frequency is said to be fundamental.
I must say that I was amazed by the content of this video. Thank you sooooooo much. The questions in the video helped fill a lot of gaps from the theory section of the video
Thank you so much! Things always make so much more sense whenever I watch your videos. You are a lifesaver and I'm definitely going to do well on these types of standing wave problems on my quiz tomorrow :)
I recently started watching your videos sir and I will like to say thanks for being so detailed in your explanations. I wioild like to ask if you could help me with this question. One end of a uniform rope of length L is tied to the ceiling while a mass M is suspended from the other force end. A transverse wave is set up at the lower end. Show that the velocity of the wave increases up along the rope. Give the expression for the time taken for the wave to reach the fixed end. Thank you so much.
Hi, @23:08 the questions stated that standing wave only has one loop. How can you have multiples wavelength with just one loop? I thought one loop= 1 wavelength.
Question; Nods represent the displacement to an anti nod... In space as a energy is transimited or Non tansit. Can we infer that the Nodes is the missing dark matter & energy we have been seeking...?
28:16 Why multiply the right side only with L? Why not multiply the before = and after = because that would make sense to me. I’m confused. Edit: and why multiply by L in the first place?

you are my god
Naaa, just kidding, but sometimes I think that
I watched this video 2hrs before my test and got a PEEFECT SCORE, your a life saver dude thanks
Nice
Yea because of this guy I have a 98% in physics and 97% in math
Don't just listen guys, try to understand
*you're
Yeah im hoping for smth like that..

😂
how could a video like this get a down vote? thanks for everything you do, your videos are great!
They probably failed their tests
cuz i dont like the way he pronounces wavelenf
probably (hopefully) by accident because i've done that a shit ton of times
Broooo thank you SO MUCH for your videos, thanks to you, I *actually survived* my AP Physics 1 test today!!!
This person is the best person I've ever witnessed in this world
You never disappoint, I always save the semester because of you. God bless You
I have understood so many concepts just from your videos!Lol!I understand you better than my professors.Thank you so much.Keep up the good work
Long live life saver. Without a physical lecture experience, you have made me confident with this content. Thk u so so much.

I freaking love the creator for making all these easy to understand videos 😭😭😭😭 literally better than lectures
I BET UR CROWNED AS THE BEST SCIENCE TUTOR. HOW LUCKY IT IS TO BE TAUGHT BY A LECTURE LIKE U DURING PHYSICAL CLASSES
I need to turn in a physics lab, but I couldn't grasp anything from my teacher, and you were incredibly helpful. Thank you!
I'm going to second all the positive comments down there. Thank you. If the online platform Mastering Physics by Pearson has me hating physics, your tutorials have the complete opposite effect. Thanks again. Great videos.
11:00 - 13 the six fundamental equations

Did u pay💀
Bro pay up
Well, let's confirm he got the job first😅
I understood this better than when my professor explained it! I couldn't do my lab report without this video. Thank you so much for explaining :)
I'm loving waves even more.
Thank you so much :)
It really helped me. 👍👍 at the start i was like what is going on
But then you just cleared all my queries.
appreciate what you do man, keep doing what u do it really helps a lot of people

thank you so much you just saved my physics test for tomorrow
i love you man you save my life everytime
You literally saved my grade in ib physics
Watching this as a review for my quiz today, I hope it goes well
I must say that I was amazed by the content of this video. Thank you sooooooo much. The questions in the video helped fill a lot of gaps from the theory section of the video
The back one are not not working.
So wht can I do
???
I think you are my mental soulmate 😊 really saved me once more
Thank u soo much... Lots of love from India🙏🙏🙏
when he said "whats the speed again?" I felt that lmfao
Thank you so much! Things always make so much more sense whenever I watch your videos. You are a lifesaver and I'm definitely going to do well on these types of standing wave problems on my quiz tomorrow :)
His explanation is so good.
absolute legend
2:10 - wavelength and L association
4:00 - harmonic frequencies
11:30 - 6 main equations
Yes, sir, I will try to do well my next exam!!
That was fantastic…Hats off
I watched this video during my test and got a PEEFECT SCORE, your a life saver dude thanks
during ur test?, bitch wtf
20:52
I don't understand until 20:58
Please, explain me!!!!!!!!!!!!!!!!!!!!!!!!!!!
DUDE i want to hug you
This video has helped me alot thank you
REALLY THANKS!!!!!! I did not understand it until I got your video!
You should be considered a hero man

You are super awesome guy👍👍
Thank u so much.. it's very helpful 💕
this looks more helpful than my teacher
Nice video 🙏🙏
Can't believe this was 7 years ago😮
Be blessed 🙏
you are a awsome teach; thank you so much for providing such a complete and perfect videos.
Thank you,for this video!🤗
Useful, Thanks
You saved me thanks
Thanks, you're a great teacher
Thank you so much bro!! Was so helpful
Thank you sir 😭🙏
You my friend are great !

*would
I don't really know which aspect to place it under waves. Thank you
I'm watching it now and I'm writing my test

thank you so much❤❤
Thanks soooo much...that was really helpful....
Thanks al lot
Thanks for the help. You kind of sound like Marky Mark.
You must be evil to give this guy a thumbs down
I really appreciate you. thanks a lot
Wonderful indeed. But, please I would like to ask, is it a must to use it the 7th harmonic, to find the first?.
Well done
20:00 How did you get f3?
You could just multiply 2.3 x 2 then divide by 4 to get both with the same n value then multiply the 1.15 by 300. I found that to be easier.
You are phenomenon
you are the best
Thank you so much
may God bless you with goodluck and fortune. Ameen
I so badly want to just drop out
Do it.
Don't do it
Man this is easy shit don’t do it
The future is your hun, do want you want ❤
الله ينور يا هندسة
Thank you!!!!!!!
Omg I love you thanks for this video
Question; Nods represent the displacement to an anti nod... In space as a energy is transimited or Non tansit. Can we infer that the Nodes is the missing dark matter & energy we have been seeking...?
How about a series on transmission line theory?
thanx dude a lot
Love you bro
Hi sir thank a lot for your video but if you make a # for the lesson more better
18:40 how did you know that the wavelength is the third harmonic?
Because if u look at the diagram there are 3 standing waves that mean the subscript you will be dealing with in that question is 3
Hey I wrote 4/3 as a whole decimal number so I got 67.5 do you think I would still get it right in the exam?
TYSMMM!
25:33 If I use fn = (vn)/(2L), I've got different answer. Could anyone please tell me why?
I got a different answer too!
Thank you sooo much for this. XOXO
Thanks

WOO!
Thanks man it usefull!!!
