Question

which wave is pictured? both longitudinal transverse neither

Explanation:

Longitudinal waves have compressions (areas where particles are close together) and rarefactions (areas where particles are spread apart). The image shows a compression, which is a characteristic of longitudinal waves. Transverse waves have crests and troughs and oscillate perpendicular to the direction of wave propagation. Since the key feature here is compression, it's not a transverse wave. And it can't be both as the features are distinct for each type in this context. Also, it's not "neither" as it fits the longitudinal wave description.

Answer:

Longitudinal
