Question

two waves of smae pitch have amplitude in the ratio 1:3


what is the ratio of
intensity
frequency

Answer 1

) Loudness is proportional to amplitude square

Ratio 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

Answer 2

Intensity: I1 : -I2=1:9 (a1²:a2²)

Frequency : -1:1 (same pitch)
