Question

the ratio of two sound is 4:9. find the ratio of the amplitude of these two sound​

Answer 1

Answer:

So, the ratio of their intensities will be 16:81. Hence, this is the required solution.

Answer 2

$\large\blue{\textsf{✩ Your Answer ✓ }}$

Let A¹ and A² are the amplitudes of two waves such that they are in ratio of 4:9. We need to find the ratio of their intensities. We know that the intensity of a wave is directly proportional to the square of its amplitude.

So, I¹/I² = (A1/A2) ²

=> I¹/I² = (4/9)²

=> I¹/I² = 16/81

So, the ratio of their intensities will be 16:81. Hence, this is the required solution.
