Earthquakes produce transverse waves. If a secondary wave of an earthquake is measured from crest to crest to be 23000 m and it travels at 4500 m/s, calculate the wave's frequency.

0.196 Hz

Explanation:

Parameters given:

Wavelength = 23000 m

Velocity = 4500 m/s

(the wavelength is the measurement from one crest to the next crest or from one trough to the next trough)

Velocity of wave is given as:

Velocity = Wavelength * frequency

Frequency can then be given as:

Frequency = velocity/wavelength

Frequency = 4500/23000 = 0.196 Hz

wavelength variability is the right one

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
