Hi, your videos are so helpful. I was just wondering if you could explain overtones to me. Does the quality/complexity increase when there are more overtones? Is there anything in particular on overtones that I am likely to be asked on a high school physics course? Thank you!
So... What ACTUALLY defines and explain the loudness of a sound [since the amplitude of a sinus wave (transversal wave, NOT longitudinal) was just a theoretical concept]?
