The Refraction of Light

The Refraction of Light. Light moves at different speeds through different media. When it travels from one medium into another, the change in speed causes the ray to bend. An analogy for refraction.

How Does Light Travel?

How Does Light Travel?. UNIT 4, LESSON 3 4-5.3. LIGHT. Light travels at a very fast speed, but travels more slowly through matter. Light travels in straight lines. Light cannot bend or turn corners, so shadows form when you block light from a source.
