For reflection of light, angle of incidence (i) and angle of reflection (r) are related as:

Q. How is the angle of incidence related to the angle of reflection ?

Q. What is the relation between angle of incidence and angle of reflection when a ray of light strikes a mirror?

Q. 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 $[\frac{\hat{i}}{2}+\frac{\sqrt{3}}{2}\hat{j}]$ & reflected ray is given by $[\frac{\hat{i}}{2}-\frac{\sqrt{3}}{2}\hat{j}],$ then angle of incidence is :-

Q. A ray of light from denser medium strikes a rarer medium at angle of incidence $i$. The reflected and refracted rays make an angle of ${90}^o$ with each other. The angle of reflection and refraction are $r$ and $r^{\prime }$. The critical angle is
