What are the different factors affecting lateral shift
Answers
The lateral displacement of light occurs because of the Refraction of light.
Anything that affects the angle of refraction affects Lateral Displacement
The Wavelength of the light used (colour) : Violet light refracts more than red light.The Material used and
Its refractive index : The higher the Refractive Index, the more the light bends.The thickness of the slab of refractive material.The angle of incidence of the light onto the incident surface of the slab.
When a denser medium is kept between two parallel faces inside a rare medium and a ray falls upon one of the two parallel faces reflects into the denser medium and comes out of another surface becoming parallel to the incident ray.
In the successive reflection the deviation at first surface is reversed at second surface but the emergent ray deviates literally.
The distance to what an emergent Ray devited from the direction of incident ray when suffers refraction at two parallel surfaces is called as lateral deviation/ displacement.
The lateral displacement/deviation increase with the increase in
• thickness
• angle of incident
• optical density
