The intensity ratio of waves is 25 : 9. What is the ratio of their amplitudes?
:18:00
:09:00
3:05
5:03
5:03
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._x000D_

So if the intensity ratio is 25:9, the amplitude ratio will be 5:3.
