At what values fo the refractive index of a recantangular prism can a ray travel as shwon in figure. The section of the prism is an isoseless triangle and the ray in normally incident onto the face `AC`.

There is a equilateral prism of refractive index 3 on which a light ray is incident normally on one face as shown in the figure. Find the length of the path traveled by the light ray inside the prism.

There is a equilateral prism of refractive index 3 on which a light ray is incident normally on one face as shown in the figure. Find the length of the path traveled by the light ray inside the prism.

A ray of light incident normally on an isosceles right angled prism travels as shown in the figure. The least value of the refractive index of the prism must be

A ray of light incident normally on an isosceles right angled prism travels as shown in the figure. The least value of the refractive index of the prism must be

The refractig angle of a prism is A and the refractive index of its material is mu .When a ray of light is incident on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.21. Determine the value of the angle of incidence in terms of A and mu .

The refractive angle of prism is A. A ray is incident normally on one of the refracting faces of a prism and emerges out. If D be the deviation of the ray then refractive index of the material of the prism is—

What is the refractive index of the material of the glass prism shown in the figure, if a ray of light incident normally at the face AB emerges along the face AC?
