When a ray of light is incident at normal incidence, (at right angles), to the surface between two optical materials, the ray travels in a straight line. When the ray is incident at any other angle, ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...

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. It is ...
