using the distance between two crests or two troughs

using the distance between compressions
using the distance between compressions

by how far apart the wave’s crest and its resting position are
by how far apart the wave’s crest and its resting position are

by how close together particles are in compressions

Answer 1

The correct response for measuring the wavelength of a longitudinal wave is:

**using the distance between compressions.**

In a longitudinal wave, the wavelength is defined as the distance between two successive compressions (or rarefactions) in the wave.
