Key Stage 3

Meaning

A Ray Diagram is a way to represent how light interacts with a boundary.

About Ray Diagrams

A Ray Diagram shows how light rays travel in straight lines.

Ray Diagrams can be used to show:

Diffuse Reflection

Diffuse Reflection allows us to see objects as the light from a light source bounces off a surface into our eyes. Diffuse Reflection happens from a rough surface.

Specular Reflection

Specular Reflection happens from a smooth surface. Specular Reflection from a mirror can be seen to follow the Law of Reflection.

Refraction

When light enters a new medium it changes direction. Light is refracted as it passes from one medium into another.
