Question
A ray of light falls on the surface of a spherical glass paper weight making an angle α with the normal and is refracted in the medium at an angle β. The angle of deviation of the emergent ray from the direction of the incident ray
Options
A.(α - β)
B.2(α - β)
C.(α - β)/2
D.(β - α)
Solution
From the following ray diagram it is clear that
δ = (α - β) + (α - β) = 2 (α - β)
δ = (α - β) + (α - β) = 2 (α - β)
