Solution:
w = 100 rad/s ; V = 200m/s ; x = 20m
Phase diff
w = 2n = 100 n = 50Hz
The angular frequency of a particle in a progressive wave in an elastic medium is 100rads-1 and it is moving with a velocity of 200ms-1. The phase difference between two particles separated by a distance of 20m is
w = 100 rad/s ; V = 200m/s ; x = 20m
Phase diff
w = 2n = 100 n = 50Hz
