The displacement function of a wave trav...

The displacement function of a wave travelling along positive x-direction is `y =(1)/(2 + 3x^(2)) at `t=0` and `y = (1)/(2) + 3(x - 2)^(2) `at ` t = 2 s`, where y and x are in metre. The velocity of the wave is

A

`2m//s^(-1)`

B

`0.5m//s`

C

`1m//s`

D

`3m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
Displacement of pulse is 2m in t=2s `implies`speed=1m/s.
