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 distance between two consecutive compressions or rarefaction. Since it is measurement of distance, its SI unit is metre
