Question

The equation of a plane progressive wave is given by the equation y = 10 sin 2π (t – 0.005x) where y and x are in cm and t in seconds. Calculate the amplitude, frequency, wave length and velocity of the wave.

Answer 1

Here 

The equation of a travelling wave is given by

Comparing the equation (i) and (ii), we have 

α = 10 cm, λ = 200 cm and v = 200 ms^–1
