Triangular Glass Prism for Light Experiments

Make a spectrum visible in a science demonstration or create a refracted-light effect in a photograph with a triangular glass prism.

Change the angle and observe the result

• ✅ Bring a spectrum into the next lesson — Glass refraction separates suitable light into visible colours.
• ✅ Try a light effect in your photograph — The prism can bend light within the planned shot.
• ✅ Pack it away between experiments — Choose the boxed variant for a supplied storage box.

Prepare the light source and background, then adjust the prism's angle slowly to find the visible effect. Comparing one position with another makes the refraction easier to discuss than holding the prism still.

For a photograph, test the placement with the camera before committing the final composition. Handle the glass carefully and use supervision around children, keeping the prism away from the eyes and unsuitable direct-sun viewing.
