Question

which kind of wave interaction is shown?
absorption
diffraction
refraction
reflection

Explanation:

Absorption is when a wave's energy is taken in by a material. Diffraction is the bending of waves around obstacles. Refraction is the bending of waves as they pass from one medium to another. Reflection is when waves bounce off a surface. In the image, the wave is bouncing off the surface, which is reflection.

Answer:

reflection
