Question

If ratio of amplitude is 3:4. What will be ratio of loudness

Answer 1

Loudness is directly proportional to the square of amplitude

Answer is:

9:16

Answer 2

Explanation:

It is given that the ratio of amplitude of two waves is 3 : 4. (i) As loudness is directly proportional to the square of the amplitude. So, the ratio of the two waves'loudness is 9 : 16
