Two waves originating from source

{S_1}\;and\;{S_2}

having zero phase difference and common wavelength

\lambda

will show complete destructive interference at a point

P

, is

({S_1}P - {S_2}P) =

View answer and explanation

Correct option: D

\frac{{11\lambda }}{2}

Option D (

\frac{{11\lambda }}{2}

) is correct because for destructive interference, the path difference must be an odd multiple of

\lambda/2

.
