Question

What are the factors on which the lateral displacement of light through a glass slab depends?

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

Answer 1

The correct option is D 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.
