A ray of light incident at an angle of incidence${\mathrm{i}}_1$ which passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and it emerges at an angle of emergence given as${\mathrm{i}}_2$. How is the given angle of emergence $‘{\mathrm{i}}_2’$ is  related to the given angle of incidence $‘{\mathrm{i}}_1’$.
