Refraction by a Prism

In a prism the two surface are inclined at same angle , so that the deviation by the first surface is not annulled by the second but is further increased . The chromatic dispersion is also increased , and this is usually the main function of a prism .In a prism the two surface are inclined at same angle , so that the deviation by the first surface is not annulled by the second but is further increased .
