Type: MCQ-conceptual-Easy-Class 12

If the monochromatic source in Young’s double slit experiment is replaced by white light, then

A

there will be a central bright white fringe surrounded by a few coloured fringes.

B

all bright fringes will be of equal width.

C

interference pattern will disappear.

D

there will be a central dark fringe surrounded by a few coloured fringes.
