Correct Answer: 5:3
Solution : The correct option is 5:3 .
A wave's amplitude squared determines how intense the wave will be. As a result, by taking the square root of the intensity ratio for two waves, we may determine the ratio of their amplitudes. The ratio of the two waves' intensities in this instance is 25:9. We may get the amplitude ratio of the two waves by taking the square root of this ratio: As a result, their amplitude ratio is 5:3.
