A ray of light is incident on the hypotenuse of a right angled prism after travelling parallel to the base inside the prism. If mu is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is

Define the Angle of the prism with respect to a prism.

A beam of light consisting of red, green and blue colours is incident on right-angled prism as shown. The refractive index 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
