A beam of light that consists of a mixture of red, green and violet light strikes a prism (surrounded by air) as shown. Indices of refraction for this prism for the various colors are indicated in the table. An observer is located to the right of the prism as shown. color n red 1.43 green 1.40 violet 1.37 Which physical phenomenon is illustrated by the fact that the emerging rays are spread into the component colors of the beam? dispersion interference total internal reflection Doppler effect diffraction

A narrow beam of white light enters a prism made of crown glass at a 45 degree incident angle, as shown below. At what angles from perpendicular to the exiting surface, do the red (660 nm) and violet (410 nm) components of the light emerge from the prism? Red light is refracted at 53.5 degrees from the perpendicular; violet light is refracted at 55.63 degrees from the perpendicular, and the difference between the angles of refraction of two colors is 0.356 degrees.

A beam of light consisting of red, green and blue colours is incident on a right-angled isosoles prism. The refractive indices of the material of the prism for the above red, green and blue wavelengths are $1.39,1.44$ and $1.47$ respectively. The prism will (a) separate part of the red colour from the green and blue colours (b) separate part of the blue colour form the red and green colours (c) separate all the three colours from one another (d) not separate even partially any colour from the other two colours
