A ray of light is incident on a parallel slab of thickness f and refractive index n. If the angle of incidence θ is small , then the displacement in then incident and emergent ray will be:
A ray of light is incident on a glass-slab from air at an angle . Thickness and refractive index of glass-slab are‘t’ and ‘μa ’ respectively, Find the lateral displacement of the emergent ray respective to incident ray.
A transparent slab of thickness d has a refractive index n(z) that increases with z. Here z is the vertical distance inside the slab, measured from the top. The slab is placed between two media with uniform refractive indices n1 and n2 (>n1), as shown in the figure. A ray of light incident with angle θi from medium 1 and emerges in medium 2 with refraction angle θf with lateral displacement l.
Which of the following statement(s) is (are) true?
