Dispersion and refraction of Light through the PRISM(Including Video)
Ray Optics Table of Content Refraction through a Prism Refraction through a Prism for Small Angle of incidence Dispersion Reason for Dispersion Refraction through a Prism Solved Problems Related Resources Refraction through a Prism A prism is a wedge-shaped body made from a refracting medium bounded by two plane faces inclined to each other at some angle. The two plane faces are called are the refracting faces and the angle included between these two faces is called the angle of prism or the refracting angle . In the below figure (1), ABC represents the principal section of a glass-prism having ∠A as its refracting angle. A ray KL is incident on the face AB at the point F where N 1 LO is the normal and ∠i 1 is the angle of incidence. Since the refraction takes place from air to glass, therefore, the refracted ray LM bends toward the normal such that ∠r 1 is the angle of refraction. If µ be the refrac...
