STANDARD Physics Young's Double Slit Experiment MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In Young's double slit experiment the ratio intensity of the maxima and minima in the inference experiment is 25 : 9. The ratio of widths of two slits is
A
18 : 3
B
4 : 1
C
8 : 1
D
16 : 1
Correct Answer
Option D
Detailed Explanation
The intensity ratio is given by (A₁ + A₂)²/(A₁ - A₂)² = 25/9. Solving for A₁/A₂ gives A₁/A₂ = 4, which means the width ratio is 16:1.
