Refraction of Light
Refraction of LightWhen a ray of light travels from one transparent medium into another medium, it bends while crossing the interface, separating the two media. This phenomenon is called refraction.
Image formation by spherical lenses is due to the phenomenon of refraction. The laws of refraction at a plane surface are equally true for refraction at curved surfaces also. While deriving the expressions for refraction at spherical surfaces, we make the following assumptions.
(a) The incident light is assumed to be monochromatic and
(b) The incident pencil of light rays is very narrow and close to the principal axis
