What is the wavelength of a wave with a velocity of 50 m/s and a frequency of 5Hz

A 250 m

B 0.1 m

C 10m

D 0.01 m

C. 10 m

Explanation:

The speed of a wave v = λf where λ is the wavelength and f the frequency of the wave.

Making λ the subject of the formula we get

λ = v/f

f = 5 Hz

v = 50 m/s

λ = 50 m/s: 5 Hz

=10 meters
