Question

Find the ratio of intensities of two waves whose ratio of loudness is 9:25​

Answer 1

Answer:

3 : 5 is the ratio of intensities of 2 waves whose ratio of loudness is 9 : 5

Answer 2

Answer:

4:5

Explanation:

The intensity of sound is directly proportional to the amplitude of the wave. i.e. I∝A^2. So if the ratio of intensities of two sound wave is 16:25; then the ratio of their amplitudes is 4:5.
