Question

what is lateral displacement of refraction through a rectangular glass slab
​

Answer 1

lateral displacement is the perpendicular dis. btw the virtual ray of incidence and exact ray os incidence

Answer 2

Lateral displacement of refraction through a rectangular glass slab

​Explanation:

• The perpendicular distance of separation between the emergent ray and the incident ray is called lateral displacement.
• It is seen that the emergent ray of light is parallel to the incident ray but displaced from the path of the incident ray after refraction through a glass slab.
• It depends upon the thickness of the glass slab, the angle of incidence and angle of refraction and since these two angles are related by refractive index, we can equally say that the lateral displacement depends upon the refraction index.
