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
(d) When two waves of same frenquency, same wavelength and same velocity moves in the same direction. Their superposition results in the interference. The two beams should be monochromatic.
