A single ray traverses a glass plate (thickness = t) with plane surfaces that are parallel to each other. The emergent ray is parallel to the incident ray but suffers a lateral displacement d. Assuming that glass plate (refractive index `mu`) is placed in air, find the dependence of d on angle of incidence i. Plot the variation of d with i (changing from `0°` to `90°`)

1.	A single ray traverses a glass plate (thickness = t) with plane surfaces that are parallel to each other. The emergent ray is parallel to the incident ray but suffers a lateral displacement d. Assuming that glass plate (refractive index `mu`) is placed in air, find the dependence of d on angle of incidence i. Plot the variation of d with i (changing from `0°` to `90°`)
Answer» Correct Answer - `d = t sin i[1-(cosi)/(sqrt(mu^(2)-sin^(2)i))]`

A large transparent cube (refractive index = 1.5) has a small air bubble inside it. When a coin (diameter 2 cm) is placed symmetrically above the bubble on the top surface of the cube, the bubble cannot be seen by looking down into the cube at any angle. However, when a smaller coin (diameter 1.5 cm) is placed directly over it, the bubble can be seen by looking down into the cube. What is the range of the possible depths d of the air bubble beneath the top surface ?
