Refraction & Reflection of Light
Investigate the reflection of light by different types of surface and the refraction of light by different substances.
In this practical you will:
- use a ray box to direct a ray of light onto the surface of a transparent block
- mark the path of the ray that is reflected from the surface of the block
- mark the path of the ray that passes through the block
- use different materials and compare the results.
The following diagram shows the incident ray, reflected ray, refracted ray and transmitted ray using a glass block.
