Question

The lateral shift in rectangular glass slab depends on

• A. Thickness of glass slab
• B. Angle of incidence
• C. Refractive index
• D. All of the above

Answer 1

The correct option is D All of the above

Angle of deviation depends on:

• Angle of incidence, i: When we change i, lateral shift changes. Note that for thin slabs, this factor is negligible.
• Thickness of slab: Lateral shift depends on the length of path of travel.
• Refractive index: Clearly, more the refractive index, more will be the bending on each face and hence, will have larger lateral shift.
