Question

Two waves of same pitch have amplitude in ratio 1:3.what will be the ratio of their ratio of
1.loudness 2.pitch ​

Answer 1

Answer:

The ratio of loudness = 1:9 and ratio of frequencies = 1:1

Explanation:

The loudness is directly proportional to the square of the amplitude of the sound wave.

The pitch is directly proportional to the frequency of the sound wave.

The ratio between the amplitude is 1:3

Therefore, the ratio between loudness is (1)²:(3)² = 1:9

The ratio between pitch is 1:1

Since the pitch is directly proportional to the frequency,

The ratio of the frequency is 1:1
