When I strike a tuning fork in the physics lab cut to vibrate at the sound of middle c on a piano, it vibrates or oscillates at
256 hertz.
If I cut a number of brass tubes to variable lengths, like wind chimes, then the shorter ones vibrate faster per second than the longer ones. So. In those terms, and viewing the earth as a giant tuning fork or sphere,...what is the basic and fundamental (note) or frequency, or wavelength of this planet?
Serious replies only if you dont mind, thank you.

Interesting question. Have a star. I don't know, but you'll have radial spherically symmetric (n) modes that cause the earth to expand and contract harmonically. The rest will involve spherical harmonics (l,m). Any geophysicists out there know the the \omega_lmn values?

The Earth's frequency was thought to be constant. When NASA started measuring this in hertz it was at 7.8. Now it is at 11.2,and has been measured as high as 14. Apparently it is still speeding up.
