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.
What else can I help you with?
What is the normal to a plane mirror?
D(power)=1\f ;f=infinity D=0 for plane mirror
What direction does a plane mirror reflect light when the beam is aimed perpendicular to it?
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.
What are the key features of a plane mirror diagram?
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.
Which mirror shows the lateral inversion of light?
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 which type of mirror are all the normals parallel to each other?
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.
What will be the reason - a plane mirror has an angle of incidence O degree?
The light ray arrives perpendicular to the plane of the mirror.

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

Which plane is Perpendicular to the longitudinal axis?
The transverse plane is perpendicular to the longitudinal axis.
Do plane mirrors have an optical axis?
Yes, plane mirrors have an optical axis, which is an imaginary line that runs perpendicular to the surface of the mirror at its center. This axis is important for understanding how light interacts with the mirror, as it helps define the direction of incoming and reflected light rays. In the case of a plane mirror, the reflection occurs symmetrically about this axis, allowing for clear images to be formed.
In which type of mirror are all the normals parallel to each other?
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.
How do you use a mirror to test a figures line of symmetry?
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.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
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.
What is a another name for a flat mirror?
A plane mirror.
