To solve the problem, we need to find the ratio of amplitudes of sound waves at points P and Q, which are at distances of 9 meters and 25 meters from a point source, respectively. ### Step-by-Step Solution: 1. **Understanding the Relationship Between Intensity and Amplitude**: - The intensity (I) of a wave is inversely proportional to the square of the distance (r) from the source. This can be expressed as: \[ I \propto \frac{1}{r^2} ...
