Question

The displacement of a wave is given by y=10/4+X2 at t=0 and Y=10/X2-4x+8 at t=1/2 seconds .the velocity of wave pulse is?

Answer 1

Explanation:

p

We know that, Formula of displacement of a wave pulse is given by y = P/{ Q+ ( vt - x² ) }

Here, Given y = 10/ { 4 + { 4t - x² } m

The given equation is directly in Standard units. so no need to change units.

If we compare, We get v = 4m/s

Therefore Velocity of the wave pulse is 4 m/s .

Hope helped!
