Flint glass prism is joined by a crown glass prism to produce dispersion without deviation. The refractive indices of these prisms for mean rays are known to be $$1.602$$ and $$1$$. $$500$$, respectively. Let the angle of prism of flint prism be $$10$$°, then what will be the angle of prism for crown prism?

Question

Infinity Learn · Accepted Answer

Use condition for Dispersion without deviation :$$($$μ−$$1)A+$$μ′−$$1A$$′$$=0$$μ$$=1.602$$,$$A=10$$∘μ′$$=1.5Substituting$$ this :$$0.602$$×$$10=0.5$$×A′A′$$=12.04$$∘$$=12$$∘$$2.4$$
