Question

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

Answer 1

The correct option is C They are linearly polarized perpendicular to each other

Two beams having the same wavelength$,$ monochromatic or white radiation$,$ having the same initial phase $($coherent sources$),$ can give interference pattern by superposition$.$ But their vibrations are perpendicular to each other$,$ interference will not be possible$.$

Hence,

option $\left(C\right)$ is correct answer.
