Light bounces off the surface of an object in a process called reflection rarefaction refraction compression

When energy is transferred from 1 point to another traveling across a medium oscillating without ousting the medium makes waves.

Wave fronts are surfaces that merge points of the same phase in waves that travel across a medium. So when wave-fronts change their course at an interface and then returns to the medium which produced it we call it Reflection.

When light (which also travels in waves) hits a surface it bounces off, just like water waves, or sound, or any other type of energy traveling that way and changing direction it's called reflection.
