A plane progressive wave on a water surface is given by the equation y=2sin2pi(100t-x/30) where x-is the distance covered in a time t, x, y and t are cm and second respectively. Find (i) the wavelength and frequency of the wave motion. (ii) the phase difference between two points on the water surface that are 60cm apart.

Answer 1

wavelength is 30m
frequency is 100 Hz
phase difference is 540 degrees

Answer 2
