Derive an expression for lateral shift and normal shift. On what factors these depends?
Answers
The Apparent shift of the ray is the perpendicular distance between the incident and the emergent ray with reference to refraction of light through a glass slab. 2.Normal Shift (NS): During refraction, the apparent shift in the position of the object along the normal is called normal.
Factors on which the Resistance of a Conductor Depends. The factor in the resistance, which takes into account the nature of the material, is the resistivity. Since it is temperature dependent, it can be used to calculate the resistance of a wire of given geometry at different temperatures
I hope this is brain list answer
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
