What is the wavelength of an earthquake wave if it has a speed of 9000 m/s and a frequency of 12 Hz?

speed = frequency x wavelength

wavelength = speed/frequency

wavelength = 9000 m/s / 12 Hz = 750 m

To find the wavelength of an earthquake wave, we can use the equation:

speed = frequency x wavelength

Given:
Speed = 9000 m/s
Frequency = 12 Hz

Plugging the given values into the equation, we can solve for wavelength:

9000 m/s = 12 Hz x wavelength

Rearranging the equation to solve for wavelength:

wavelength = speed / frequency

Substituting the values, we get:

wavelength = 9000 m/s / 12 Hz

Calculating the result:

wavelength = 750 m

Therefore, the wavelength of the earthquake wave is 750 meters.
