Question

When we clap our hands, the sound produced is best described by
(a) p=p0 sin(kx-ωt)
(b) p=p0 sin kx cos ωt
(c) p=p0 cos kx sin ωt
(d) p=∑p0n sin (knx-ωnt).
Here p denotes the change in pressure from the equilibrium value.

Answer 2

When we clap our hands, the sound produced is best described by p=∑p0n sin (knx-ωnt).

Explanation:

p=∑p0n sin (knx-ωnt).

• Here p denotes the change from the equilibrium value in pressure.

• When we clap, different regions of both palms don't strike with the same pressure each other.
• Therefore various regions of the palms produce different sounds with different amplitudes of pressure, Wave and frequency numbers.
• Thus the pressure at a point at that moment is given as a summation of the pressure at that point.
