Question
An earthquake wave has a wave length of 523m and travels with a speed of 4.6km through a portiin of Earths crust.
a) what is its frequency?
b) if it travels into a different portion of Earths crust, where its speed is 7.5km/s,what is its new wavelength?

L = 523 m.
V = 4.6 km/s. = 4600 m/s.
a. L = V*(1/F) = V/F = 523 m
4600/F = 523
523F = 4600
F = 8.8 c/s = 8.8 Hz.
b. L = V/F = 7500/8.8 = 852.3 m.
V = 4.6 km/s. = 4600 m/s.
a. L = V*(1/F) = V/F = 523 m
4600/F = 523
523F = 4600
F = 8.8 c/s = 8.8 Hz.
b. L = V/F = 7500/8.8 = 852.3 m.
