Assertion (A) : In interference and diffraction of light, light energy reduces in one region producing a dark fringe. It increases in another region and produces a bright fringe.
Reason (R) : This happens because energy is not conserved in the phenomena of interference and diffraction.
Official answer
(C)
Assertion (A) is true, but Reason (R) is false.
