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
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.
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.
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 :)
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?
12:50 You claimed that antinodes are counted at *maximum* displacements and *minimum* displacements. 14:34 You didn’t count the *minimum* displacements but just counted the *maximum* ones. Was this a mistake or am I missing something?
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.
Hey, I'm slightly confused on how you calculated the wavelengths at 23:00. I was under the impression that wavelength = 2L/n, so can you walk me through this one please? Thx
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!
22:37 answer is not correct because I f I use the formula that states that the wavelength is equal to 2L/n and plug in 12 for L and 5 for n it will come out as 4.8(plugged in 5 for n cause he said the fifth harmonic ) am I correct or I am just dumb
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?

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

Well, let's confirm he got the job first😅
when he said "whats the speed again?" I felt that lmfao
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.
2:10 - wavelength and L association
4:00 - harmonic frequencies
11:30 - 6 main equations
I freaking love the creator for making all these easy to understand videos 😭😭😭😭 literally better than lectures
appreciate what you do man, keep doing what u do it really helps a lot of people
I'm loving waves even more.
Thank you so much :)
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 need to turn in a physics lab, but I couldn't grasp anything from my teacher, and you were incredibly helpful. Thank you!

I don't really know which aspect to place it under waves. Thank you
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
Wonderful indeed. But, please I would like to ask, is it a must to use it the 7th harmonic, to find the first?.
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!
Nice video 🙏🙏

The FamilyBennett you will get the same answer wavelength = 2L/n , L=2 and n=1 so wavelength = 2 Times 2 /1 = 4m
@@TeamArrow-l4f I’m 3 years late but isn’t L = 12m? From where did you get the 2?

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 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
Thank you sooo much for this. XOXO

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

may God bless you with goodluck and fortune. Ameen
Thanks man it usefull!!!
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.
n is the number of loops or harmonics and L is the length of the string
How about a series on transmission line theory?
