Reflection and Refraction Practicals

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.
