Place a prism (P 1 ) on a table and a screen behind it. Allow a narrow beam of light to be incident on the prism (P 1 ). The white light gets dispersed and we obtain a band of seven colors on the screen. Recomposition of the Dispersed White Light Now remove t..

. And let i be the angle of incidence and r the angle of refraction. If the incident ray TP is extended forward and the emergent ray RO backwards, they meet at M, forming the angle OML. Measure the angle OML. This angle is called the angle of deviation. Angle of deviation is the angle through which..
