Question
Based on the problem solution provided in the text (with distances rA=5m, rB=3m, rC=9m), at which point is the sound intensity the highest?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Sound intensity is inversely proportional to the square of the distance (I ∝ 1/r²). Therefore, the point closest to the source will have the highest intensity. Among 5m, 3m, and 9m, 3m (Point B) is the shortest distance.
Hint
Intensity decreases with distance. The shortest distance corresponds to the highest intensity.
