Answer 1

Answer:

2:1

Beats are produced with the help of two sound waves of amiplitudes 3 and 5 units. The ratio of maximum to minimum intensity in the beats is. 2:1. 5:3.

Explanation:

Answer 2

Answer:

Intensity Is proportional to the amplitude squared.

So, maximum intensity will be observed when there will be constructive interference or maximum amplitude and similarly minimum intensity when there'll be destructive interference or when the superposition amplitude will become minimum.

So, I max / I min = (3+5)^2/(5-3)^2 = 64/4 = 16

So, the ratio of max intensity and min intensity is 16:1
