Question

Two waves of the same pitch have amplitudes in
the ratio 1: 3. What will be the ratio of their
(1) loudness, (ii) pitch?​

Answer 1

Answer:

Correct option is

C

1:9

Loudness depends on the square of the amplitude of the wave.

That is, loudness∝(amplitude)

2

Thus, when the ratio of amplitudes of the wave is 1:3, the loudness becomes 1:9.
