The stationary wave`y = 2a sin kx cos omega t` in a closed organ pipe is the result of the superposition of `y = a sin (omega t - kx)`

A

`y = a cos(omegat- kx)`

B

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

C

`y = a sin(omegat- kx)`

D

`y = a cos(omegat+ kx)`

Text Solution

Verified by Experts

The correct Answer is:
D
Potential across the capacitor is zero, hence energy stored is zero.
