Question

a wave hits a wall as shown. as the wave interacts with a wall, which kind of wave interaction is shown?

Explanation:

The wave hits the wall and then bounces off, changing direction. This is the definition of reflection, where a wave encounters a boundary (the wall) and returns, maintaining its wave nature but reversing direction (or following the law of reflection for angles). Refraction involves bending due to medium change, diffraction is spreading around obstacles, and absorption is energy transfer, none of which match here.

Answer:

Reflection (the wave interaction shown is reflection, as the wave hits the wall and bounces back, changing its direction of propagation, consistent with the behavior of wave reflection at a boundary).
