Sir, I have a doubt. At 1:30 you mentioned that as the medium particles outside the organ pipe scatter the density decreases. That part I got sir. But right after that you mentioned that speed of sound increases? This happens to be my doubt. Sir, sound is a longitudinal wave. It requires a material medium for propagation. So as the density of the medium decreases the number of particles in the vicinity, which were to carry the sound wave (or the disturbance or energy) decreases. This only implies that the speed of sound should increase sir. So should the speed of sound decrease or increase sir? Please forgive me if I am wrong sir.
