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.

Angles of incidence and refraction are always measured between the normal and the corresponding ray of light. Direction of refraction. Glass is denser than air, ...

Refraction occurs when light changes direction as it passes, e.g., from air into water or glass. Negative refraction, however, is a counterintuitive effect where light in a medium bends in the ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction.

The higher the index of refraction, the slower light travels in that medium. In air, n = 1.00027. In water, n = 1.333. ... Remember we said glass has a high index of refraction?
