The perpendicular to a plane mirror is a line that is at a 90-degree angle to the mirror's surface. It is important for understanding the reflection of light rays off the mirror's surface, as the angle of incidence is equal to the angle of reflection with respect to this perpendicular line.
D(power)=1\f ;f=infinity D=0 for plane mirror
A plane mirror reflects light back in the same direction from which it came, regardless of the angle of incidence. This means that if the beam of light is aimed perpendicular to the mirror, it will be reflected back along the same path.
A plane mirror diagram shows the reflection of an object in a mirror. Key features include the object, its reflection, the mirror surface, and the normal line perpendicular to the mirror. The angles of incidence and reflection are equal, and the image appears to be the same distance behind the mirror as the object is in front.
This refers to the apparent left-right reversal often shown by the image in a plane (flat) mirror. Lateral means "sideways". In fact it's something of an illusion, because the inversion is really in the direction perpendicular to the mirror surface.
In a plane mirror, all the normals (imaginary lines perpendicular to the surface) are parallel to each other. This means that the reflection angle is equal to the incident angle, resulting in a virtual image that appears to be the same distance behind the mirror as the object is in front of it.
The light ray arrives perpendicular to the plane of the mirror.

A line is perpendicular to a plane when it is perpendicular on two lines from the plane

The transverse plane is perpendicular to the longitudinal axis.

Stand the mirror perpendicular to the figure. When it is positioned on the line of symmetry, the image in the mirror should be the same as the original image. However, this only works with your line of sight being the correct plane.
If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.
A plane mirror.
A simple way to locate to image in a plane mirror without using light rays is to measure the distance of the object itself to the mirror and then draw a dotted line that is equal to the distance of the object-mirror on the other side. Then connect the sides to the end of the line. i had to do this in science today :)
