Solution
The correct option is A is plane
The Law of Reflection A ray of light strikes
a plane mirror and light ray reflects off the mirror. Reflection involves a
change in direction of the light ray
and the angle of the
incident light ray is equal to the angle of the reflected light ray. The normal line
is to the surface of the mirror that
makes a 90 degree angle to the mirror. This line is used as a reference point
for all of the angles.
The angle of incidence is the angle
that the incident ray makes the normal and the angle of reflected angle that the reflected ray makes with the
normal.
