A crown glass prism of refracting angle $6^{o}$ is to be used for deviation without dispersion with a flint glass of angle of prism $α$ . Given: for crown glass $μ_{r} = 1.513$ and $μ_{v} = 1.523,$ for flint glass $μ_{r} = 1.645$ and $μ_{v} = 1.665 .$ What should be the value of $α$ ?

Options:

Answer:

Solution:

$\Rightarrow (μ_{V_{1}} - μ_{r_{1}}) α_{1} = (μ_{V_{2}} - μ_{r_{2}}) α_{2}$

or $\Rightarrow α_{2} = \frac{(1.523 - 1.513)}{(1.665 - 1.645)} 6^{o} = 3^{o}$
