A wave is represented by the equation y ...

A wave is represented by the equation `y = a sin(kx + omega t)` is superimposed with another wave to form a stationary wave such that the point x = 0 is a node. Then the equation of other wave is :-

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
`y_(res)=y+y=0("at"x=0)rArr a sin (kx-omegat)+y'=0`
put x=0 and get `y_(res)=0`
