The wave function of a pulse is given by

y=\frac{3}{(2 x+3 t)^2}

where

x

and

y

are in metre and

t

is in second.

i) Identify the direction of propagation.

ii) Determine the wave velocity of the pulse.

View answer and explanation

Correct option: A

-1.5 \mathrm{~m} / \mathrm{s}

Option A (-1.5 m/s) is correct because the wave is propagating in the negative x-direction and the velocity is determined by the ratio of the coefficients of t and x.
