Which of the following travelling wave will produce standing wave , with nodes at `x = 0`, when superimosed on ` y = A sin ( omega t - kx)`

A

`A sin(omegat + kx)`

B

`A sin(omegat + kx + pi)`

C

`A cos (omegat +kx)`

D

`A cos (omegat + kx + pi)`

Text Solution

Verified by Experts

The correct Answer is:
B
Substituting x = 0 we have given wave y = A sin omegat at x = 0 other should have y = -A sin omegat equation so displacement may be zero at all the time.
