Opposite Rays

Consider the following figure of line vec(MN) . Say whether following statements are true or false in context of the given figure. Ray OM is not opposite ray vec(OP)

An isosceles prism of angle 120degree has a refractive index 1.44. Two parallel monochromatic rays enter the prism parallel to each other in air as shown. The rays emerge from the opposite faces

The opposite faces of a glass slab of thickness 15 cm are parallel. If a ray of light is incident on the glass slab at an angle 60^(@) , calculate the lateral displacement of the ray when it emerges from the slab. [mu " "" of glass" = 1.5]

An isosceles prism of angle 120degree has a refractive index 1.44. Two parallel monochromatic rays enter the prism parallel to each other in air as shown. The rays emerge from the opposite faces

A parallel beam of light is incident on a prism as shown in figure. Such that the rays get reflected from opposite faces. The angle of deviation delta between reflected rays from faces AB and AC is-

An isosceles prism of angle 120^(@) has a refractive index of 1.44. Two parallel monochromatic rays enter the prism paralled to each other in air as shown. The rays emerging from the opposite faces

Find the angle of incidence of a ray of light on one face of a 60°.prism, if the ray is just totally reflected on meeting the opposite face (refractive index of glass = 1.5).

In Figure,ray OE bisects /_AOB and OF is a ray opposite to OE. Show that /_FOB=/_FOA

In the given figure, ray OC is the bisector of angleAOB and OD is the ray opposite to OC. Show that angleAOD=angleBOD .
