As the mirror changes direction, the light reaching the mirror can reach the ceiling because the light --

• travels in straight lines and reflects from the surface of the mirror

• refracts in the glass of the mirror and is spread out all over the room

• enters the mirror and changes direction when it is refracted by the back of the mirror

• travels through air and does not change its direction in air

Which sentence explains accurately what happens when you direct light waves at an angle into mirror?

• Light waves strike the surface of the mirror and are reflected in many directions.
