The roots of the Rayleigh characteristic equation for surface waves are obtained under the assumption that the square of the ratio of the velocities of volume waves is a rational number. The exact formulas for the roots contain a minimum of radicals and rational numbers.
Keywords: surface waves, Rayleigh wave velocity, roots of the characteristic equation, exact formulas.
