The energy in the phenomenon of interference-

A

is conserved, gets redistributed

B

is equal at every point

C

is destroyed in regions of dark fringes

D

is created at the place of bright fringes.

Text Solution

Verified by Experts

The correct Answer is:
A
In interference pattern we can see that resultant amplitude of super imposed wave depends on the phase difference of waves so it varies from maximum to minimum amplitude by redistributing of energy but total energy remains conserved.
