A right angled hollow prism is filled with a liquid. A ray of light entering prism grazing one face emerges out grazing other face. Refractive index of liquid is

A narrow beam of monochromatic light, PQ, is incident normally on one face of an equiangular glass prism of refractive index 1.45 . When the prism is immersed in a certain liquid, the ray makes a grazing emergence along the other face (figure). Find the refractive index of this liquid .

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 narrow beam of monochromatic light, pe, is incident normally on one face of an equiangular glass prism of refractive inder 1-45. When the prism is immersed in a certain liquid, the ray makes a grazing emergence along the other face (See below figure). Find the refractive index of this liquid.

A light ray is incident on one refraction face of a prism, of refractive angle A, at an angle of incidence, I and emerges from the opposite face, normally. If refractive index of the material of the prism be mu what will be the value of the angle of incidence?

A ray of light is incident at angle of incident ,I, on one face of a prism of angle A (assumed to be small) and emerges normally from the opposite face. If the refractive index of the prism is mu the angle of incidence i, is nearly equal to:
