Question

A plane mirror produces a magnification of-
A. Zero
B. -1
C. +1
D. Between 0 and +1

Answer 1

Hint: A plain mirror is a mirror with a smooth reflecting (planar) top. The angle of reflection exceeds the angle of intensity of light rays, which hit a flat mirror. The point of incidence is the corner from the incident ray to the regular surface (a perpendicular to the base line).

Step-By-Step answer:
The angle of reflection is also the distance of the mirrored ray from the usual and a collimated light beam does not extend out except for diffraction results after reflecting the plane mirror. A plain mirror reflects objects in front of a mirror, which seem to be in the backdrop of the plane in which the mirror is mounted. A right line drawn from part of an object to its reflection makes the top of the plane mirror a right angle and is separated by it. A plane mirror reflection is also synthetic (i.e. light rays do not always originate from the reflection). This picture is upright and has the same form and scale as the entity mirrored. A virtual image is a copy of an object that is formed at the site of the light rays. But the image is a "mirror image" of the object laterally inverted. The reflection of a right hand seems to be the left hand of the camera if a human sees his reflection in the plane mirror.
A plane mirror magnification of +1 signifies that the created image is virtual, erect, of the same size as an object.
Hence, option C is the correct option.

Note: Plane mirrors are the only form of mirror where a real object often creates a true, upright and medium-sized image. Nevertheless, simulated artifacts generate actual images. There is no end to the focus length of a mirror plane; the optical strength is zero.
