Vedclass · Answer

(A) The deviation $\delta$ produced by a prism is given by $\delta = i + e - A$. For a given deviation $\delta$ (where $\delta > \delta_{min}$),there are two possible values of the angle of incidence $i$ and angle of emergence $e$,such that $i_1 = e_2$ and $i_2 = e_1$. This is a direct consequence of the principle of reversibility of light,which states that if the path of a light ray is reversed,it will retrace its original path. Thus,the Reason correctly explains why there are two angles of incidence for the same deviation.
