A wave representing by the equation y = ...

A wave representing by the equation `y = a cos(kx - omegat)` is suerposed with another wave to form a stationary wave such that point `x = 0` is a node. The equation for the other wave is

A

`a sin (kx + omegat)`

B

`-a cos(kx + omegat)`

C

`-a cos(kx - omegat)`

D

`-a sin(kx - omegat)`

Text Solution

Verified by Experts

The correct Answer is:
B
As `x = 0` is node `rArr` standing wave should be `y = 2a sin kx omegat`
Now solve
