The ends of a stretched wire of length L...

The ends of a stretched wire of length `L` are fixed at `x = 0 and x = L`. In one experiment, the displacement of the wire is `y_(1) = A sin(pi//L) sin omegat` and energy is `E_(1)` and in another experiment its displacement is `y_(2) = A sin (2pix//L ) sin 2omegat` and energy is `E_(2)`. Then

A

`E_(2) = E_(1)`

B

`E_(2) = 2E_(1)`

C

`E_(2) = 4E_(1)`

D

`E_(2) = 16E_(1)`
