Answer:
See below.
Explanation:
A parabolic reflector reflects the incident rays, coming from the light source placed at the focus, along the principal axis ( i.e parallel to it ). So, we get a beam of high-intensity light in the direction along the principal axis.
It reflects most of the light on the front side so as to have maximum illumination there.
This is evident from the diagram attached.
