Question:

A ball of radius R = 50 cm is located in the way of propagation of a plane sound wave. The sonic wavelength is λ = 20 cm, the frequency is v = 1700 Hz, the pressure oscillation amplitude in air is (∆p)m = 3.5 Pa. Find the mean energy flow, averaged over an oscillation period, reaching the surface of the ball.
