Q. Two beams of light will not give rise to an interference pattern, if
A) They are coherent
B) They have the same wavelength
C) They are linearly polarized perpendicular to each other
D) They are not monochromatic
Explanation
(c) Two beams having the same wavelength, monochromatic or white radiation, having the same initial phase (coherent sources), can give interference pattern by superposition. But when their vibrations are perpendicular to each other, interference will not be possible
