A crown glass prism of refracting angle$6°$is to be used for deviation without dispersion with a flint glass of angle of prism$\mathrm{\alpha }$. Given: for crown glass${\mathrm{\mu }}_{\mathrm{r}}=1.513$and${\mathrm{\mu }}_{\mathrm{v}}=1.523$, for flint glass${\mathrm{\mu }}_{\mathrm{r}}=1.645$and${\mathrm{\mu }}_{\mathrm{v}}=1.665$. Find$\mathrm{\alpha }$
