Answer:
A. two adjacent compressions
Step-by-step explanation:
A wave is transverse if the oscillations occur at a right angle (transverse) to the direction of wave propagation. This kind of wave creates characteristic hills and down. Transverse waves include all-natural electromagnetic waves, rope waves, water waves, waves generated by the marketing of taut wire.
A wave is longitudinal if the oscillations occur along (along) the direction of wave propagation. The longitudinal wave creates characteristic places of thickening and thinning of the environment. Longitudinal waves include:
sound wave, elastic wave, laser beam
