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 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, 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 at an angle of 60^@ on the face of a prism having refracting angle 30^@. The ray emerging out of the prism makes an angle 30^@ with the incident ray. Show that the emergent ray is perpendicular to the face through which it emerges and calculate the refractive index of the material of prism.
