Question

How is the loudness of sound related to:

(i) amplitude of the vibrating body

Answer 1

Hint:

Knowledge of sound waves

Step 1:

Amplitude of the vibrating body:

1. Sound waves are longitudinal waves, and frequency can be defined as the number of wave cycles generated per second.
2. The maximum displacement of media particles from the average position is called wave amplitude.
3. The reaction of the ear to the frequency of sound is called pitch.
4. The phenomenon of sound waves that depends on the amplitude and energy of the sound waves is called loudness.
5. Sound waves are considered loud if the amplitude of the sound is high.

Because the loudness depends on the amplitude of the sound wave.
