Answer:
•A longitudinal wave consists of a repeating pattern of compressions and rarefactions. Thus, the wavelength is commonly measured as the distance from one compression to the next adjacent compression or the distance from one rarefaction to the next adjacent rarefaction.
Explanation:
- Sound waves are composed of compression and rarefaction patterns. Compression happens when molecules are densely packed together. Alternatively, rarefaction happens when molecules are distanced from one another.
- Compression- a region in a longitudinal (sound) wave where the particles are closest together. • Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart.
