A sound wave of frequency 512hz and amplitude 2.4 x 10^–3m is going through air of density 1.293kg/m³. Find the intensity of wave. Velocity of sound in air is 330m/s.

Solution

Given that,
Frequency of the sound wave = 512 Hz
Amplitude of the sound wave = 2.4 $cross times$ 10^-3 m
Density of air = 1.293 kg/m³
Intensity of the wave is,
