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.

Broooo thank you SO MUCH for your videos, thanks to you, I *actually survived* my AP Physics 1 test today!!!

11:00 - 13 the six fundamental equations

appreciate what you do man, keep doing what u do it really helps a lot of people

It really helped me. 👍👍 at the start i was like what is going on But then you just cleared all my queries.

I'm loving waves even more. Thank you so much :)

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 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

You never disappoint, I always save the semester because of you. God bless You

I freaking love the creator for making all these easy to understand videos 😭😭😭😭 literally better than lectures

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 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

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.

His explanation is so good.

man am loving your videos continue makin more

REALLY THANKS!!!!!! I did not understand it until I got your video!

That was fantastic…Hats off

you are a awsome teach; thank you so much for providing such a complete and perfect videos.

Thanks, you're a great teacher

Yes, sir, I will try to do well my next exam!!

You my friend are great !

thank you so much you just saved my physics test for tomorrow

Thank u soo much... Lots of love from India🙏🙏🙏

This person is the best person I've ever witnessed in this world

Thank you,for this video!🤗

Thank you so much bro!! Was so helpful

Watching this as a review for my quiz today, I hope it goes well

excellent tutor ,,,, just incredible guy God bless you and maybe he give u more energy as you change life of scholars

i love you man you save my life everytime

Thank u so much.. it's very helpful 💕

Thanks soooo much...that was really helpful....

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.

Useful, Thanks

Love your videos man

بارك الله فيك

I really appreciate you. thanks a lot

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's super great ,, thanks

I think you are my mental soulmate 😊 really saved me once more

excellent lecture 😍😍😍

Thanks man it usefull!!!

when he said "whats the speed again?" I felt that lmfao

Thank you so much

Thank you sooo much for this. XOXO

I so badly want to just drop out

Nice video 🙏🙏

thank you so much

Thanks al lot

You are super awesome guy👍👍

Great thanks a lot...

Thank you!!!!!!!

thanx dude a lot

Thanks

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.

TYSMMM!

Be blessed 🙏

Love you bro

DUDE i want to hug you

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.

I don't really know which aspect to place it under waves. Thank you

Wonderful indeed. But, please I would like to ask, is it a must to use it the 7th harmonic, to find the first?.

this looks more helpful than my teacher

Nice

How about a series on transmission line theory?

I have the following problem could you please help me to solve it? 3. A spring and mass system with a mass of 2.5 kg is observed to have a frequency of 5.5 Hz. What is the stiffness constant of the spring?

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?

You should be considered a hero man

25:33 If I use fn = (vn)/(2L), I've got different answer. Could anyone please tell me why?

@abdullahbabor4876

I got a different answer too!

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 saved me thanks

Thanks for the help. You kind of sound like Marky Mark.

What does 'n' and 'L' represent? I have been following velocity (wave speed m/s), frequency (Hz) and lambda (wavelength), so I'm a bit confused.​

@ruthsatoro3821

n is the number of loops or harmonics and L is the length of the string

may God bless you with goodluck and fortune. Ameen

Can someone explain why there are different types of standing waves created whenever you pluck a string?

Hi sir thank a lot for your video but if you make a # for the lesson more better

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.

Can't believe this was 7 years ago😮

i love you

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...?

18:40 how did you know that the wavelength is the third harmonic?

@renae9450

4 жыл бұрын

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

can someone tell me in 21:05 lambda(n) = lambda(1)/n but in the next line its lambda(1) = nlambda(n)? parenthesis represent subscripts

22:41

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!

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?
