Question

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

• A. Thickness of block
• B. The angle of incidence
• C. The refractive index of glass
• D. The wavelength of light used

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A

Thickness of block

B

The angle of incidence

C

The refractive index of glass

D

The wavelength of light used

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 wavelength of light used.
$\to$ Lateral displacement increases with the decrease in wavelength.
