In a Young's experiment,the paths from the slits to a point on the screen differ in length,causing destructive interference at the point.Which of the following path difference would cause this destructive interference?
A)5λ/2
B)3λ/4
C)4λ
D)None of the above.

Question

Quizplus · Accepted Answer

Destructive interference occurs when the path difference is an odd multiple of half-wavelengths, such as (2n+1)λ/2. Here, 5λ/2 is an odd multiple of λ/2, causing destructive interference.
