This was made possible through the understanding of the basic principles of optics and ... property of prisms in this article is their ability to redirect light through refraction and reflection.

When a ray of light is incident at normal incidence, (at right angles), to ... frequency has a greater refractive index than lower frequency light. This explains why a prism can disperse white ...

Dove prisms can be thought of as right-angle prisms with the triangular apex removed, which reduce the weight of the prism and stray internal reflections. They introduce astigmatism when used with ...
