AIIMS 2000 Physics Interference MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Ratio of intensities of two waves is 9 : 1. If these two are superimposed, what is the ratio of maximum and minimum intensities?
A
9 : 1
B
3 : 1
C
4 : 1
D
5 : 3
Correct Answer
Option C
Detailed Explanation
The ratio of maximum to minimum intensity is given by (a + b)² : (a - b)² where a and b are the amplitudes. Since intensity is proportional to amplitude squared, the ratio is 4:1.
