STANDARD Physics Interference MCQ Question
Type: MCQ-numerical-Medium-Class 12
Two slits in Young's double slit experiment have widths in the ratio 81 : 1. The ratio of the amplitudes of light waves is
A
3 : 1
B
3 : 2
C
9 : 1
D
6 : 1
Correct Answer
Option C
Detailed Explanation
The amplitude ratio is proportional to the square root of the intensity ratio. Given the width ratio β₁/β₂ = 81/1, the amplitude ratio A₁/A₂ = √(I₁/I₂) = √(81/1) = 9/1.
