A ray of light falls normally on one face of a prism of angle `45^@`. If critical angle for material of the prism is `45^@`, trace the course of rays, calculate `mu`.

A ray of light incident normally on one face of a prism ( mu =2) undergoes grazing emergence . The angle of the prism is

A ray of light is incident normally on one face of a prism of refracting angle A. After travelling through prism, the ray emerges from the second refracting surface making an angle of deviation of delta . The refractive index of the material of prism is

A monochromatic ray of light in incident normally on a refracting face of a prism of angle 30^(@) . The refractive index of the material of the prism 1.5 . The angle of emergence will be

A ray of light is incident on a prism of refracting angle A. if theta_(C) is the critical angle for the material of the prism with respect to the surrounding air, then:

A ray of light falls normally on one face of a right angled prims of refracting angle A. It suffers two total internal reflections before coming out of prism parallel to incident ray as shown. Refractive index to prism material will be:
