1.	The intensity ratio of waves is 25 : 9. What is the ratio of their amplitudes?
Answer» 5 : 3 In general, the INTENSITY of a wave is PROPORTIONAL to the SQUARE of its amplitude. This has an important IMPLICATION: relative intensity can be obtained by SQUARING relative amplitude. I α a² So if the intensity ratio is 25:9, the amplitude ratio will be 5:3.

Answer»

5 : 3

In general, the INTENSITY of a wave is PROPORTIONAL to the SQUARE of its amplitude. This has an important IMPLICATION: relative intensity can be obtained by SQUARING relative amplitude.
I α a²
So if the intensity ratio is 25:9, the amplitude ratio will be 5:3.
