reflected.

Window

Window

The window is transparent.The light is

The light is transmitted but “jumbled”.

Reflection vs. Refraction

Reflection vs. Refraction

• Light bouncing off of a surface.

Reflection vs. Refraction

• Light bouncing off of a surface.

• Light bends because it changes speeds as it changes mediums.
