What happens when a wave is reflected from the surface of a boundary?

The refracted waves are the waves that are transmitted across the boundary and continue moving downwards, only at a different angle than before. When a light ray reflects off a surface, the angle of incidence is equal to the angle of reflection.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
