Question

Define thin Prism, Derive expression for angle of deviation of thin prism.​

Answer 1

Answer:

δm is the minimum deviation produced in the given prism, the minimum deviation occurs when the angle of incidence is equal to the angle of emergence. For a thin prism, the apex angle A is very small. This implies that the refraction edge of the prism is also small. ... This is the required prism formula for a thin prism.
