Type: MCQ-conceptual-Medium-Class 11
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
(√I₁ − √I₂)²
B
2(√I₁ + √I₂)
C
I₁ + I₂
D
(√I₁ + √I₂)²
Correct Answer
Option B
Detailed Explanation
The maximum intensity is (√I₁ + √I₂)² and the minimum intensity is (√I₁ − √I₂)². Their sum is 2(√I₁ + √I₂).
