Define the term angle of deviation.
Write a relation for the angle of deviation (δ) for a ray of light passing through an equilateral prism in terms of the angle of incidence (i1) angle of emergence (i2) and angle of the prism (A).
A ray of light incident at an angle of incidence i1 passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges at an angle of emergence i2.
- How is the angle of emergence ‘i2’ related to the angle of incidence ‘i1’.
- What can you say about the angle of deviation in such a situation?
How does the angle of deviation depend on the refracting angle of the prism?

The angle between two plane rectangular refracting surfaces of a prism is called as
The diagram below shows the path of a blue ray through the prism:
