Question

Which of the following is not relevant to a plane mirror?
(a)Causes dispersion of light
(b)Reflects light
(c) Produces lateral inversion
(d)Produces virtual image
​

Answer 1

• A plane mirror has a reflecting surface that is flat (planar).

• The angle of reflection equals the angle of incidence for light rays striking a planar mirror.

• The angle of incidence is the angle formed by the incident ray and the normal of the surface (an imaginary line perpendicular to the surface).

• With the exception of diffraction effects, the angle of reflection is the angle between the reflected ray and the normal, thus a collimated beam of light does not expand out after reflection from a flat mirror.

• A plane mirror reflects items in front of it, but these reflections appear to be behind the plane in which the mirror is located.
• A straight line traced from one section of an item to the corresponding part of its image forms a right angle with the plane mirror's surface and is bisected by it.
• The image generated by a plane mirror can be virtual (meaning that the light rays do not truly originate from the picture) or real (meaning that the light rays do come from the image) (meaning that the light rays do actually come from the image).
• It is, however, always upright and the same form and size as the item it reflects.
• A virtual picture is a representation of an item created at the spot where light rays appear to originate.
• Option a is correct
• Causes dispersion of light

Answer 2

• The distance between the image obtained is that the same because of the distance between the thing from the mirror. The image shape is virtual. the scale of the image is that the same because of the size of the thing. The image shaped is laterally inverted.
• A plane mirror incorporates a reflective surface that's flat (planar).
• The angle of reflection equals the angle of incidence for lightweight rays placing a planate mirror.
• Causes dispersion of light is not relevant to a plane mirror.
