Question

name the physical quantity which determine the pitch of sound depends.

Answer 1

Frequency determines the pitch of sound.
Hope it helps u.

Answer 2

Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitchmeans very rapid oscillation, and "low" pitchcorresponds to slower oscillation.ie it depends on frequency
