Question

If a wave is traveling at 200 m/s and its wavelength is 0.5 meters, what is the frequency of the

wave?

Answer 1

The frequency of the wave = 400/s

Further explanation

Given

v=200 m/s

λ=0.5 m

Required

The frequency of the wave

Solution

Frequency (f): number of waves in one second

The frequency is inversely proportional to the wavelength

`\tt f=(v)/(\lambda)\\\\f=(200~m/s)/(0.5~m)\\\\f=400/s`
