What is the wavelength of an earthquake wave if it has a speed of 9000 m/s and a frequency of 12 Hz? a 9012 m b 108,000 m c 750 m d 0.0013 m

The formula to calculate the wavelength of a wave is given by:

Wavelength = Speed / Frequency

Substitute the given values:
Wavelength = 9000 m/s / 12 Hz
Wavelength = 750 m

Therefore, the wavelength of the earthquake wave is 750 m. The correct answer is c) 750 m.
