The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction …

Learn about refraction, ray diagrams and how convex lenses bend light rays with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

Refraction involves two related parts, both a result of the wave nature of light: a reduced speed in an optical medium and a change in angle when a wave front crosses between different media …

Oct 3, 2025 · Learn about refraction for your IGCSE Physics exam. This revision note includes ray diagrams and an explanation on the refraction of light investigation.

Refraction can cause virtual images of objects to appear where light seems to be coming from. A ray of light curves as it passes through glass, perspex or water. Use a perspex block with the …

Figure 5.9: The diagram shows the boundary between two media: water and air. An incoming light ray is refracted when it passes through the surface of the water into the air.

This page takes a close look at the refraction of a ray of red light at the boundary between air and glass. Related topics including reflection and dispersion are covered on other pages of this …

In this video, we'll walk you through the process of drawing ray diagrams for refraction using a glass block and calculating the refractive index of glass.

In this diagram, the right hand side of the incoming wave slows down before the left hand side does. This causes the wave to change direction. Learn about and revise reflection and …
