The refraction of light in glass prism is different from a glass slab. This is because in glass prism, the incident ray of light is not parallel to emergent ray of light.

Everything CCEA students need to know about the reflection and refraction of light for GCSE Physics. BBC Homepage. Skip to content; ... It can be seen when white light is split by a prism, ...

His glass prisms not only let light pass through but also redirected it sideways into the room. ... ray II is converged by the prism refraction, and ray III is recycled by other prisms.

In other words, a prism seems only to bend (refract) light, leaving it otherwise unaltered. But it does so to different degrees (that is, at different angles) for different colors.
