On the face of it part 1

Calculate the angle of incidence on the face of a prism of refracting angle 60^(@) and of refractive index 1.5, for which the emergent ray just grazes the other face.

A ray incident on the face of a prism is refracted and escape through an adjacent face. What is the maximum permissible angle of the prism, if it is made of glass with a refractive index of mu=1.5 ?

At what angle should a ray of light be incident on the face of a prism of refracting angle 60^(@) so that it just suffers total internal reflection at the other face ? The refractive index of the prism is 1.524.

A point charge q is placed at the centre of a cube. What is the flux linked. a with all the faces of the cube? b. with each face of the cube? c. if charge is not at the centre, then what will be the answer of parts a and b ?

A ray of light incident at an angle theta on a refracting face of a prism emerges from the other face normally. If the angle of the prism is 5^@ and the prism is made of a material of refractive index 1.5 , the angle of incidence is.

A ray of light incident at an angle theta on a refracting face of a prism emerges from the other face normally. If the angle of the prism is 5^@ and the prism is made of a material of refractive index 1.5 , the angle of incidence is.

A glass prism is immeresed in water as shown in the figure. When a beam of light incident is incident normally on the face ab, it is internally reflected at the face ad. If the refractive index of glass is 1.5 and that of water is 4//3 , then

A ray of light incident at an angle theta on a refracting face of a prism emerges from the other face normally. If the angle of the prism is 5^@ and the prism is made of a material of refractive index 1.5 , the angle of incidence is.
