Type: MCQ-conceptual-Medium-Class 12
Two periodic waves of intensities I₁ and I₂ pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities is
A
2(I₁ + I₂)
B
I₁ + I₂
C
(√I₁ + √I₂)²
D
(√I₁ - √I₂)²
Correct Answer
Option A
Detailed Explanation
The maximum intensity is given by (√I₁ + √I₂)² and the minimum intensity by (√I₁ - √I₂)². Their sum is 2(I₁ + I₂).
