At what distance is the image formed behind the plane mirror?
For plane mirrors, the object distance (is equal to the image distance. That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must look at a location 2 meters behind the mirror in order to view your image.
How do you mathematically verify that the image formed by a plane mirror is virtual?
Reflection from the Plane Mirror The ray OP is perpendicular to the mirror and hence, reflects back along PO. The incident ray OD and the reflected ray DE make equal angles with the normal DG. The two reflected rays when produced backwards meet at I, producing a virtual image there. ∠GDO = ∠DOI (DG || IO).
In which mirror image is formed behind the mirror?
Section Summary. The characteristics of an image formed by a flat mirror are: (a) The image and object are the same distance from the mirror, (b) The image is a virtual image, and (c) The image is situated behind the mirror. A convex mirror is a diverging mirror and forms only one type of image, namely a virtual image.
How is a plane mirror formed?
A plane mirror is made using some highly reflecting and polished surface such as a silver or aluminium surface in a process called silvering. After silvering, a thin layer of red lead oxide is applied at the back of the mirror.
How do you describe the image formed in plane mirrors?
Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object’s distance, and the same size as the object.
What is the mirror formula for curved mirrors?
1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
Which statement is true about the image produced by a plane mirror?
The image formed by a plane mirror is always a virtual image. The image always appears to be located the same distance behind the mirror as the object is located in front of the mirror.
Is the image formed in a plane mirror always behind the mirror?
The image formed in a plane mirror is indeed behind the mirror – how far it is depends on the distance of the object – it’s exactly the same distance. So the question is erroneous. I shall take the liberty of restating it as: “…prove that the image formed in a plane mirror is behind the mirror, equidistant with the object”.
What is mirror equation and how to use it?
What is Mirror Equation? It is an equation relating object distance and image distance with focal length is known as a mirror equation. It is also known as a mirror formula. In a spherical mirror:
What are the sign conventions for magnification and mirror equation?
The sign conventions for the given quantities in the mirror equation and magnification equations are as follows: d i is + if the image is a real image and located on the object’s side of the mirror. d i is – if the image is a virtual image and located behind the mirror.
What is the distance from the object to the mirror?
This means that the distance PB from the object to the mirror is the same as the distance BQ from the mirror to the image. The object distance (denoted ) is the distance from the mirror to the object (or, more generally, from the center of the optical element that creates its image).
