Interference of light corresponds to conservation of energy because

A. All fringes are of equal width.
B. All bright fringes are of same intensity and the dark fringes are of same intensity.
C. All fringes are separated by equal distance.
D. Energy is transferred from dark fringe to bright fringe.

Choose the correct answer from the options given below:

B and D only

The correct answer is Option (2) → B and D only

In case of constructive interference, intensity becomes maximum & bright fringes are formed on the screen having same intensities whereas in destructive interference, intensity being minimum dark fringes are formed on screen. This implies that in interference intensity of light is redistributed from dark to bright fringe.
