A ray of light is incident on an equilateral triangular prism parallel to its base as shown in the figure. The ray just fails to emerge from the face AC. If `mu` be the refractive index of the prism then the relation(s) is/are :

A ray of light incident on an equilateral triangular glass prism of mu = sqrt(3) moves parallel to the base of the prism inside it. What is the angle of incidence for this ray ?

A ray of light incident on an equilateral triangular glass prism of mu = sqrt(3) moves parallel to the base of the prism inside it. What is the angle of incidence for this ray ?

A ray of light is incident horizontally on the face AB of the.right angled prism as shown in the figure. If the ray emerges grazing the surface AC, find the value of phi . Refractive index of the material of the prism is given to be n.

A ray of light incident on an equilateral glass prism propagates parallel to the base line of the prism inside it. Find the angle of incidence of this ray. Given refractive index of material of glass prism is sqrt(3) .

Two light rays 1 and 2 are incident on two faces AB and AC on an isosceles prism as shown in the figure. The rays emerge from the side BC. Then,

A ray of light falls on a normally on a refracting face of a prism. Find the angle of prism if the ray just fails to emerge from the prism (mu=3//2).
