Sound waves from a point source are propagating in all directions. What will be the ratio of amplitudes at 9m and 25m from the sources?
Added by Michael W.
Step 1
The intensity of a sound wave is inversely proportional to the square of the distance from the source. So, we can write the intensity at 9m and 25m as: $I_1 = \frac{k}{9^2}$ and $I_2 = \frac{k}{25^2}$, where k is a constant. Show more…

For a sound coming from a point source, the amplitude of sound is inversely proportional to the distance. If the displacement amplitude of an air molecule in a sound wave is $4.8 \times 10^{-6} \mathrm{~m}$ at a point $1.0 \mathrm{~m}$ from the source, what would be the displacement amplitude of the same sound when the distance increases to $4.0 \mathrm{~m} ?$
A point source emits sound equally in all directions in a nonabsorbing medium, Two points P and Q are at distance of 2m and 3m respectively from the source. The ratio of the intensities of the waves at P and Q is (a) 9 : 4 (b) 2 : 3 (c) 3 : 2 (d) 4 : 9
