Refraction Through a Glass Block | GCSE Physics

A set of GCSE Physics diagrams illustrating the refraction of light through a rectangular glass block, including the incident ray, refracted ray, emergent ray, normal, and angles of incidence, refraction and emergence.

These diagrams show how light changes direction as it enters and leaves a glass block, with the emergent ray parallel to the incident ray but laterally displaced. Transparent-background downloads make the diagrams easy to incorporate into presentations, worksheets and other teaching materials.

Flexible for teaching and assessment

Four versions included

• Labelled | colour

• Labelled | printable

• Recall | colour

• Recall | printable

The labelled versions can be used to introduce and explain the features of refraction through a glass block. The recall versions replace the labels with blank boxes, allowing students to practise identifying the rays, normal and angles.

The high-contrast greyscale versions are designed specifically for printing and photocopying, while the colour versions work well for presentations, digital resources and classroom displays.
