Which of these describes a wave being reflected?

the wave encounters some obstacle or change in medium. the wave bounces off the surface and moves in a different direction, but at an angle equal to the one at which it hit the surface.

the wave encounters some corner or a small opening. the wave bends and fans out, forming an arc.

two waves move towards each other and the crest of each wave overlaps, creating a new wave that has a greater amplitude than either individual wave.

the wave encounters some change in medium. the wave moves through the new medium in a different direction, but at an equal angle at which it hit the surface.
