Reflection occurs when a wave hits boundary between two media where the wave speeds differ, but the wave stays in the original medium instead of passing into the second medium. ... Refraction is the change of the propagation direction of waves when they pass into a medium where they have a different speed.

How does light reflection and refraction propagation?

What is reflection and refraction of light waves?

Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another.
