Problem

Two prisms each of apex angle

5^{\circ}

are made of different optical glasses. For the same monochromatic light, the refractive indices are

\mu_1 = 1.46

(silica) and

\mu_2 = 1.62

(flint). (i) Calculate separately the approximate deviations

d_1

and

d_2

produced by the two prisms. (ii) Determine the ratio

d_2/d_1

and comment on which prism produces the larger deviation and why.
