Question

The speed of sound in air is 332 m s⁻¹. Is it advisable to define the length 1 m as the distance travelled by sound in 1/332 s?

Answer 1

No, it is not advisable to define the length 1 m as the distance travelled by sound in 1/332 s because the speed of sound is affected by various factors such as temperature, humidity and nature of medium. So, it cannot be said that the distance travelled by sound in 1/332 s will be 1 m, less than 1 m or more than 1 m.
