The wave function of a pulse is given by...

The wave function of a pulse is given by y= `(3)/((2x+3t)^(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.

Text Solution

Verified by Experts

Since the given wave function is of the form y=f(x + vt), therefore, the pulse travels along the negative X-axis.
(ii) since `2x+3t`= constant
Therefore, by differentiating with respect to time we get `2(dx)/(dt)+3= or v =(dx)/(dt)=(-3)/(2)=-1.5m//s`
