A prism of refractive index 2 and apex angle A is in air as shown Light is incident from PQ side at an angle of incidence i 0 i 90 Choose the correct options R A if A 40 then light incident at all angles will be refracted at surface PR B If A 80 then light incident at some angles will be refracted and at some other angles light will be reflected at surface PR C If A 920 then light incident at all angles will be reflected at surface PR D whatever is the value of A light definitely emerge from the surface PR
