Question

pre assessment- student a. longitudinal wave b. transverse wave c. ultraviolet wave d. radio wave

Explanation:

The slinky in the diagram shows oscillations (side-to-side hand motion) that are perpendicular to the direction the wave travels along the slinky. This matches the definition of a transverse wave, where particle motion is perpendicular to wave propagation. Longitudinal waves have parallel particle/wave motion, while ultraviolet and radio waves are electromagnetic waves that do not require a medium like a slinky.

Answer:

B. Transverse wave
