NEET Physics Interference MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Two light beams of intensities in the ratio of 9 : 4 are allowed to interfere. The ratio of the intensity of maxima and minima will be:
A
2 : 3
B
16 : 81
C
25 : 169
D
25 : 1
Correct Answer
Option D
Detailed Explanation
The intensity ratio of maxima to minima in interference is given by (I₁ + I₂)²/(I₁ - I₂)². Substituting the given intensity ratio, the result is 25:1.
