, which can be the bending of sunshine when it passes from 1 medium to a different of different density—e.g., from air to glass. The glass is generally known as a lens and could have a number of components. The Bodily condition of your elements may very well be convex, concave, or aircraft-parallel. This diagram illustrates the basic principle of refraction as well as the expression focal length. The main focus is The purpose, or plane, at which mild rays from infinity converge just after passing by way of a lens and touring a length of 1 focal size.

Such as, if the target features a focal length of 254 cm (one hundred inches) as well as eyepiece includes a focal duration of two.fifty four cm (one inch), then the magnification will probably be one hundred.
