Question

Based on the amplitude, what can be determined?

• A. Timbre
• B. Loudness
• C. Frequency
• D. Pitch

Answer 1

The correct option is B

Loudness

Explanation for correct option:

Option (B):

1. Amplitude is the maximum displacement of the vibrating body on one side.
2. Loudness of sound is proportional to the square of the amplitude of the vibration producing the sound.
3. Thus with increase in amplitude loudness becomes the square of amplitude

Explanation for incorrect option(s):

Option A:

1. Timbre is the characteristic that helps us to distinguish two sounds having the same pitch and loudness.

Option C:

1. Frequency tells oscillations of the sound waves per second.

option D:

1. Pitch depends on the frequency of the sound wave.

Hence, Option (B) is the correct option.
