Question

two waves of same pitch have anplitudes in the ratio 1:3.What will be the ratio of their loudness and pitch​

Answer 1

Answer:

1:9

Explanation:

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

That is, loudness∝(amplitude)^2

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