Question

Wavelength of a sound wave is defined as:

• A. time between occurrence of two peaks/valleys
• B. distance between two peaks/valleys
• C. density gap between peaks/valleys
• D. pressure difference between two peaks/valleys

Answer 1

The correct option is B

distance between two peaks/valleys

Wavelength of a sound wave is defined as the distance between two consecutive crests or troughs. Since it is the measurement of distance, it's S.I. unit is metre.
