Question

The wave function of a pulse is given by y=5/(4x+6t2), xand y are in meter and t is in second velocity of pulse is ?

Answer 1

3/2 will be the velocity

Answer 2

Given :

The wave function of a pulse is given by :

$y=\dfrac{5}{(4x+6t)^2}$

To Find :

The velocity of pulse .

Solution :

The velocity is given by :

$v=\dfrac{\text{coefficient of t}}{\text{coefficient of x}}\\\\v=\dfrac{6}{4}\ m/s\\\\v=1.5\ m/s$

Therefore , the velocity of pulse is 1.5 m/s .
