Sound Pressure on Spheres

Abstract

The theory of King for the radiation pressure exerted by plane progressive waves on spheres has been used to compute the constants for spheres of radii (r) of the order of a wave-length (λ) of the sound in the medium. These are given for integer values of α = 2πr/λ from 1 to 11, and for α = 15 and 20. For larger α the constants approach a limiting value so that one may use a simple approximation to obtain the constants for such spheres.
