What is reflection of light? Explain the laws of reflection.

Reflection of light is the phenomenon of bouncing back of light rays into the same medium when they strike a polished surface.
Laws of reflection:
$(i)$ The incident ray,the reflected ray,and the normal to the surface at the point of incidence all lie in the same plane.
$(ii)$ The angle of incidence $(i)$ is equal to the angle of reflection $(r)$,i.e.,$\angle i = \angle r$.
