Define the following terms:
$(i)$ Angle of incidence
$(ii)$ Angle of reflection
$(iii)$ Plane of incidence

(N/A) $(i)$ Angle of incidence: It is the angle between the incident ray and the normal at the point of incidence.
$(ii)$ Angle of reflection: It is the angle between the reflected ray and the normal at the point of incidence.
$(iii)$ Plane of incidence: It is the plane that contains the incident ray,the reflected ray,and the normal at the point of incidence.
