Question

1.Write any three characteristics of sound waves.​

Answer 1

Answer:

Characteristics of Sound

Sound produced by any means has the following characteristics, namely, loudness, pitch or shrillness, and quality or timbre.

Loudness

The loudness of sound depends on its amplitude. The loudness of sound is proportional to the square of the amplitude. A roar of a lion is louder than a woman’s voice. The loudness of sound is measured in Decibel (db). If loudness exceeds 80 db, then the sound becomes physically painful.

Pitch

The pitch of sound depends on its frequency. If frequency is more, then the pitch or shrillness is more. The pitch of a woman’s voice is more and it is shriller then a man’s voice.
