WebDec 5, 2024 · This process can be done using Snell’s law of refraction, but a few tricks can simplify the process too. For example, a ray that passes through the center of the lens is barely deflected at all, and one that strikes the lens perpendicular to the optical axis is refracted to pass through the focal point for the lens. WebJun 24, 2024 · Physically speaking refraction is a very broad term; it generally describes the process of light passing from one medium into another and the effects this has on its speed and direction. A prism for example affects light of different wavelengths differently and splits white light up into the colours of a rainbow.
