A plane progressive wave is represented by the wave equation:
Where y is in millimetres, t is in seconds, and x is the distance from a fixed origin, O, in metres. Find:
The frequency of the wave
The wavelength of the wave
The speed of the wave
The phase difference, in radians between a point 0.25 m from ‘O ‘and a point 1.10 m from ‘O’.
The equation of a wave travelling in the same medium with double the amplitude, and double the frequency, but travelling in the opposite direction.
