NEET Physics Interference MCQ Question
What is the condition for destructive interference to occur at a point in the interference pattern?
The path difference equals (n + 1/2)λ for n = 0, 1, 2, ...
The path difference equals nλ for n = 0, 1, 2, ...
The phase difference is 0 degrees.
The path difference equals 2nλ for n = 0, 1, 2, ...
Correct Answer
Detailed Explanation
Destructive interference occurs when the path difference between two waves equals (n + 1/2)λ, leading to a cancellation of the waves and zero intensity at that point.
