Physics - Geometrical Optics Question with Solution | TestHub

Law of reflection states that when a light ray is incident on a reflecting surface then angle of incidence (i) = Angle of reflection (r). If incident ray is given by $\left[\frac{\hat{i}}{2}+\frac{\sqrt{3}}{2}\hat{j}\right]$ \& reflected ray is given by $\left[\frac{\hat{\mathrm{i}}}{2}-\frac{\sqrt{3}}{2}\hat{\mathrm{j}}\right]$, then angle of incidence is :-
