Problem

y = 2\sin(100\pi t - 5\pi x)

, where

y

and

x

are in centimetres and metres respectively and

t

is in seconds. At the fixed position

x = 0.25\,\text{m}

, find the phase difference between the instants

t_1 = 0.020\,\text{s}

and

t_2 = 0.024\,\text{s}

. Express your answer in radians.
