Name the colour of white light which is deviated

(i) the most,

(ii) the least, on passing through a prism.

Which of the two prisms, A made of crown glass and B made of flint glass, deviates a ray of light more?

How does the deviation produced by a prism depend on

(i) the refractive index of its material, and

(ii) the wavelength of incident 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.

(i) How is the angle of emergence 'i₂' related to the angle of incidence 'i₁'.

(ii) What can you say about the angle of deviation in such a situation?
