Question

With increase in amplitude of the sound wave, loudness increases.

• A. True
• B. False

Answer 1

The correct option is A True

Sound: Sound is a mechanical wave, so to propagate its material medium is required.

1. Loudness increases with an increase in the amplitude of the wave or increase in the surface area of the source or an increase in intensity. it is independent of frequency.
2. The loudness of a sound is determined by its amplitude. When the amplitude is increased, the sound becomes louder.

Hence the given statement is true.
