Question

why is drawing normal in reflection is important?​

Answer 1

Answer:

The ray of light that leaves the mirror is known as the reflected ray. ... We need the normal line, in any case, so that we might measure the angles with respect to the surface normal, as it divides the angle between the incident ray and the reflected ray into two equal angles".
