A Simplified Approach to the Mechanics of Acoustical Wave Propagation Applicable to the Problems of Radiation Pressure: Part II: The Application to Rayleigh and Langevin Radiation Pressure
The formulae derived in part I of this paper are applied to Rayleigh and Langevin pressures. By doing this the magnitude of both pressures can be calculated. The magnitude of the Langevin pressure, p L, appears to be twice the mean kinetic energy density in the medium due to the wave. In isomorphium this relationship holds exactly, in any other medium it will hold to second order approximation. The magnitude of the Rayleigh pressure, p R, appears to be given by the relationship p R = (α – 1) p L which α is the non-linearity parameter as denned in part I of this paper. Also this relationship holds exactly in the case where the medium consists of isomorphium.
