Question

two waves of the same pitch has amplitude in the ratio 1 : 3. what will be the ratio of their (i) loudness (ii) pitch?​

Answer 1

Answer:

Loudness is 1:9

Pitch is 1:1

Explanation:

Loudness is dependent on amplitude.

Frequency is dependent on pitch.

Answer 2

Answer: $\frac{1}{9}$

Explanation:

loudness ∝ (ampplitude) ²

so,

$\frac{1}{3}$= $\frac{1^2}{3^2}$ = $\frac{1}{9}$
