Question

two waves of same pitch have amplitudes in the ratio 1:3. What will the ratio be of their intensities and frequencies?

Answer 1

Dear student,

(i) Intensity is the measure of Loudness, which is proportional to amplitude squared
Hence, the Ratio of loudness= $1/3^2=1:9$
(ii) The frequency of the sound wave has no effect on amplitude.
so, ratios of frequency remain the same that is 1:1
