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.
