उत्तर
The angle of deviation, represented by 8 (delta), is the angle formed by the direction of the incident ray generated forward, and the emerging ray produced backward.

The deviation produced by a prism is independent of the angle of incidence and is same for all the colours of light.
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?
Which of the two prism, A made of crown glass and B made of flint glass, deviates a ray of light more?

A ray of light incident at an angle of incidence 48° on a prism of refracting angle 60° suffers minimum deviation. Calculate the angle of minimum deviation.
[Hint: δmin = 2i - A]
Draw a ray diagram showing the dispersion through a prism when a narrow beam of white light is incident on one of its refracting surfaces. Also indicate the order of the colours of the spectrum obtained.
