Once these incident rays strike the lens, refract them according to the three rules of refraction for converging lenses. The ray that passes through the focal point on the way to the lens will refract and travel parallel to the principal axis.

Snell's law (also known as Snell–Descartes law and ibn-Sahl law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air. In optics, the law is used in ray tracing to compute the angles of incidence or refra… WebRefraction (optics) Refraction is the phenomenon that causes a light ray to bend when it hits an optical lens surface (or other medium that can act to transmit light e.g. water). …

WebJan 6, 2016 · The light that reflects of the bottom half of the pencil travels first through water and then through air. As light crosses the boundary between these two media (plural for medium) it bends. This phenomenon is called refraction. This refraction of light creates the appearance of a bent pencil as shown in the figure.
