What is the path difference of destructive interference

View answer and explanation

Correct option: D

\frac{{\left( {2n + 1} \right)\lambda }}{2}

Option D (

\frac{{\left( {2n + 1} \right)\lambda }}{2}

) is correct because destructive interference occurs when the path difference is an odd multiple of half the wavelength.
