The intensity of a wave is 0.02 W/m². What is its amplitude if the proportionality constant is 1?
Q1. The intensity of a wave is 0.02 W/m². What is its amplitude if the proportionality constant is 1?
Answer: 0.141 m
Explanation: Intensity is proportional to amplitude^2. So, amplitude = sqrt(intensity) = sqrt(0.02) = 0.141 m. Option A is incorrect due to miscalculation.
