AIIMS 2001 Physics Interference MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Two coherent monochromatic light beams of amplitude 3 and 5 units are superposed. The maximum and minimum possible intensities in the resulting beams are in the ratio
A
4 : 2
B
16 : 1
C
8 : 2
D
4 : 2
Correct Answer
Option B
Detailed Explanation
The maximum intensity is proportional to the square of the sum of amplitudes, and the minimum intensity is proportional to the square of the difference. Thus, (3+5)² : (5-3)² = 64 : 4 = 16 : 1.
