The periods of them are computed by solving the governing ordinary differential equations singular at the Earth center using the Chebyshev collocation method.

The ordinary differential equations of the free oscillation of the Earth are solved by using the Chebyshev collocation method for removing their singularity at the Earth center and high accuracy result is obtained.
