The separatio...

Question

The separation between two consecutive crests in a transverse wave is 100 m. If wave velocity is 20 m $s^{- 1}$ , find the frequency of wave.

Open in App

Solution

Separation between two consecutive crest = Wavelength
Wavelength = 100 m
Velocity = 20 m/s

Frequency = Velocity / wavelength
= 20/100
= 0.2 Hz

Frequency is 0.2 Hz
