To find the speed of waves, use this formula!
V = frequency x wavelength

V = 31.08 m/s
*m/s is meters per second.

the geosphere describes all of the rocks, minerals and ground that are found on and in Earth. This includes all of the mountains on the surface, as well as all of the liquid rock in the mantle below us and the minerals and metals of the outer and inner cores.
