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

Answer»

(i) Loudness is proportional to amplitude squareRatio of loudness= 1/3square = 1:9(ii) Frequency of the sound wave has no effect on amplitude.so, ratios of frequency remains same that is 1:1
