A progressive wave y = A sin (k x - `omega`t) is reflected by a rigid wall at x = 0 . Then the reflected wave can be represented by -

A

`y=a sin (kx+omega t)`

B

`y=a cos (kx+omega t)`

C

`y=-a sin (kx-omegat)`

D

`y=- a sin (kx+omega t)`

Text Solution

Verified by Experts

The correct Answer is:
D
Given,
progressive wave `y= a sin (kx-omega t)`
When reflected by rigid wall.
Progressive wave `y'=a sin [(k(x)+omegat)xx lambda]`
or `y'=-a sin [(kx+omega t)]`
