What is the path difference for destructive interference (if n is an integer)? |
$nλ$ $(n+1)\frac{λ}{2}$ $(2n+1)\frac{λ}{2}$ $(n+1)λ$ |
$(2n+1)\frac{λ}{2}$ |
Destructive interference occurs when the path difference is odd intergral multiple of $\frac{\lambda}{2}$ i.e $(2n+1)\frac{λ}{2}$. The correct answer is Option (3) → $(2n+1)\frac{λ}{2}$ |
