Four independent light waves are expressed as

\mathrm{y}_1=\mathrm{a}_1 \sin \omega \mathrm{t}, \mathrm{y}_2=\mathrm{a}_2 \sin \omega \mathrm{t}, \mathrm{y}_3=\mathrm{a}_3 \cos \omega \mathrm{t}

and

\mathrm{y}_4=\mathrm{a}_4 \sin (\omega \mathrm{t}+\pi / 3)

. The interference is possible between

View answer and explanation

Correct option: D

Not possible at all

The correct answer is D (Not possible at all) because independent light waves are generally incoherent and cannot produce sustained interference patterns.
