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