The important property of prisms in this article is their ability to redirect light through refraction and reflection. A collection of deck lights used to direct sunlight below deck in ships.

Light of higher frequency has a greater refractive index than lower frequency light. This explains why a prism can disperse white light into different colours. The change in refraction is quite ...

The film covers topics such as the speed of light, the principles of reflection and refraction, the functioning of lenses and prisms, and the nature of different types of light, including lasers.

The prism bends different colours of light at different angles. This is called refraction. This can happen in raindrops too. When sunlight enters a raindrop the different colours of light are ...
