Question

9). the wave above is (circle one)
a) transverse
b) longitudinal
c) compression
d) gravity

Explanation:

To determine the type of wave, we recall the definitions: Transverse waves have oscillations perpendicular to the direction of wave propagation (e.g., light, water waves with up - down motion). Longitudinal waves have oscillations parallel to the direction (e.g., sound, with compressions and rarefactions). Compression is a part of a longitudinal wave, not a wave type. Gravity waves are a specific type related to gravity - driven disturbances. Since the question likely refers to a typical wave like a water wave (or the common context of wave types), transverse waves have the characteristic of perpendicular oscillation. So the correct option is a.

Answer:

a) Transverse
