Question

What is the wavelength of an earthquake wave if it has a speed of 8 km/s and a frequency of 3 Hz?

Answer 1

Answer:

2666.67 m

Explanation:

Changing the 8km/s into SI units we 8000m/s.

Speed of a wave = λf where λ is the wavelength and f he frequency of the wave.

v=λf

Therefore making wavelength the subject of the formula we get

λ= v/f

Substituting with the values in the question we get:

λ= (8000m/s)/3Hz

=2666.667 m

Answer 2

The answer is 266666
