NEET Physics Interference MCQ Question
What is the condition for destructive interference in terms of path difference between two coherent sources?
The path difference is equal to (n + 1/2) λ.
The path difference is equal to n λ.
The path difference is zero.
The path difference is greater than λ.
Correct Answer
Detailed Explanation
Destructive interference occurs when the path difference is given by (n + 1/2) λ, resulting in the waves being out of phase and canceling each other out.
