shows a snapshot of a wave-form of frequency `50 Hz`. For this wave motion, find
(a) wavelength
(b) amplitude
( c) velocity.
.

Explanation

Here, `v = 50 Hz`
(a) Wavelength = distance between two consecutive crests.
=`lamda = 25 cm - 5 cm = 20 cm`
(b) Amplitude = `4 cm`
( c) Wave velocity, `v = v lamda = 50 xx 20`
`= 1000 cm//s = 10 m//s`.
