QUESTION:
A small fraction of the energy in a sound wave is absorbed by the air through which the sound passes. How does this modify the inverse-square relationship between intensity and distance from the source? Explain.
ANSWER:Solution 12DQ Step 1: The equation for the intensity of the sound wave, I = P/4r 2 Where, P = power dissipated from sound wave source r = Distance which the sound wave travels
