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.
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
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.
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.
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.
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...?
Dear Sir If we have displacement U(x,t,wn,n) with defined parameter, how we can estimate the frequency response? (With x: position, t: time, wn: in your video is c*n*pi/L, n is harmonic number) In frequency response, i want to find and compare the magnitude of displacement with resonance frequency!
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.
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 a real one
god bless you
you deserve a hug homie saved my life cramming for my exam in a couple hours
🐐
@13:41
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
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.
Did u pay💀
Bro pay up
Well, let's confirm he got the job first😅

11:00 - 13 the six fundamental equations
I need to turn in a physics lab, but I couldn't grasp anything from my teacher, and you were incredibly helpful. Thank you!
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 BET UR CROWNED AS THE BEST SCIENCE TUTOR. HOW LUCKY IT IS TO BE TAUGHT BY A LECTURE LIKE U DURING PHYSICAL CLASSES
It really helped me. 👍👍 at the start i was like what is going on
But then you just cleared all my queries.
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.
I freaking love the creator for making all these easy to understand videos 😭😭😭😭 literally better than lectures
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 :)
Watching this as a review for my quiz today, I hope it goes well
appreciate what you do man, keep doing what u do it really helps a lot of people

The back one are not not working.
So wht can I do
???
His explanation is so good.
thank you so much you just saved my physics test for tomorrow
2:10 - wavelength and L association
4:00 - harmonic frequencies
11:30 - 6 main equations
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 love you man you save my life everytime
Thank u soo much... Lots of love from India🙏🙏🙏
Yes, sir, I will try to do well my next exam!!
You literally saved my grade in ib physics
That was fantastic…Hats off
absolute legend
I watched this video during my test and got a PEEFECT SCORE, your a life saver dude thanks
during ur test?, bitch wtf
I think you are my mental soulmate 😊 really saved me once more
REALLY THANKS!!!!!! I did not understand it until I got your video!
when he said "whats the speed again?" I felt that lmfao
excellent tutor ,,,, just incredible guy
God bless you and maybe he give u more energy as you change life of scholars

I don't really know which aspect to place it under waves. Thank you
This video has helped me alot thank you
you are a awsome teach; thank you so much for providing such a complete and perfect videos.
DUDE i want to hug you
You should be considered a hero man
Thanks, you're a great teacher
thank you so much OCT
this looks more helpful than my teacher
man am loving your videos continue makin more
Thank you so much bro!! Was so helpful
It's super great ,, thanks
Love your videos man
You are a godsend
You my friend are great !
I'm watching it now and I'm writing my test
Thanks for the help. You kind of sound like Marky Mark.
excellent lecture
😍😍😍
Thank u so much.. it's very helpful 💕
You saved me thanks
Be blessed 🙏
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.
Thank you,for this video!🤗
You are super awesome guy👍👍
Useful, Thanks
Can't believe this was 7 years ago😮
may God bless you with goodluck and fortune. Ameen
بارك الله فيك
Thanks soooo much...that was really helpful....
Wonderful indeed. But, please I would like to ask, is it a must to use it the 7th harmonic, to find the first?.
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 ❤
Thank you sir 😭🙏
Nice video 🙏🙏
thank you so much❤❤
I really appreciate you. thanks a lot
You must be evil to give this guy a thumbs down
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?
Well done
You are phenomenon
Hi sir thank a lot for your video but if you make a # for the lesson more better
How about a series on transmission line theory?
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...?
Omg I love you thanks for this video
you are the best
Thank you so much
Thanks al lot
الله ينور يا هندسة
Can someone explain why there are different types of standing waves created whenever you pluck a string?
Harmonic is integral multiple of fundamental.
Thank you sooo much for this. XOXO
thanx dude a lot
Dear Sir
If we have displacement U(x,t,wn,n) with defined parameter, how we can estimate the frequency response?
(With x: position, t: time, wn: in your video is c*n*pi/L, n is harmonic number)
In frequency response, i want to find and compare the magnitude of displacement with resonance frequency!
@Zain Ahmad Thank u so muchhhhh! 😁
Thank you!!!!!!!
Thanks
Love you bro
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.
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
20:52
I don't understand until 20:58
Please, explain me!!!!!!!!!!!!!!!!!!!!!!!!!!!
How do we get paid off of the energy that they seap from the land on our property? Or where where renting or Staying or renting or living
what if the nodes are on a vibrating loop, then the nodes would = antinodes right?
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?
