Great video as usual. Keep it up Sir

You sir are amazing! I bet these videos take a lot of time and effort to make, but they are informative and really make things much easier to understand. Thank you very much!

Thankyou Daniel

Isn't the fundamental frequency the 1st harmonic, and the one with 2 antinodes the 2nd and so on?

love it

Thank you sir! But I still have some questions. When we plunk a guitar string, the initio shape of the string is like a triangle with a corner above the sound hole. I can view this shape as a combination of infinite waves with different wave lengths. These wave lengths definitely include the wavelengths 2L, L, 1.5L, .... But why these frequencies correspond to the n th harmonics stand out? (We can see the peaks on the n th frequency) Why the frequencies corresponding to wavelengths other than 2L, L, 1.5L, 0.5L , (and so on) can not be discovered at the frequency domain?

That's a great wave animation showing constructive and destructive interference in a standing wave. Where can I find this animation for my students to play with?

it is in the description

Ooops! 1st harmonic is the same as the fundamental and 2nd harmonic is the same as the 1st overtone and 3rd harmonic is the same as the 2nd overtone etc.

Well. This is half true. You don't see knows in the wave when you play the guitar, because is the wave has energy losses in each movement of the wave to come and go, in addition to interacting with the other waves. In fact, I have never seen knots on a guitar string. The differential equations for waves in progressive losses do not show this behavior. The behavior of the string is rather a compound wave with decreasing amplitude over time.
