Question

What are the factors on which the lateral displacement (d) of light through a glass slab does not depend on?

• A. The thickness of the glass slab
• B. The mass of the glass slab
• C. The angle of incidence
• D. The refractive index of glass

Answer 1

The correct option is B The mass of the glass slab

i) Dependence on the thickness of the medium:
$\to$ More the thickness of the medium, more is the lateral displacement.

ii) Dependence on the angle of incidence:
$\to$ More the angle of incidence, more is the lateral displacement.

iii) Dependence on the refractive index:
$\to$ More the refractive index of the medium, more is the lateral displacement.

iv) Dependence on the mass of the glass slab:
$\to$ Lateral displacement depends on optical density, that does not depend on mass.
