A ray of incident on an equilateral prism shows minimum deviation of `30^(@)` .The speed of light through the prism is ?

A ray of light incident on face AB of an equilateral glass prism, shows minimum deviation of 306@ .Calculate the speed of light through the prism.

(i) A ray of light incident on face AB of an equilateral glass prism, shows minimum deviation of 30^(@) . Calculate the speed of the light through the prism. (ii) Find the angle of incidence at face AB so that the emergent ray grazes along the face AC.

If minimum deviation = 30^(@) , then speed of light in shown prism will be

An equilateral prism produces a minimum deviation of 30^(@) . The angle of incidence is

A ray of light when incident upon a prism surface a minimum deviation of 39^@ If the shaded half portion of the prism is removed, then the same ray will -

A monochromatic light is incident at a certain angle on an equilateral triamgular prism and suffers minimum deviation . If the refractive index of the material of the prism is sqrt(3) , them the angle of incidence is :
