Questions Related to characteristics of an image formed by a plane mirror

Which type of an image is formed by a plane mirror?

evs reflection of light by plane surfaces characteristics of an image formed by a plane mirror formation of image in a plane mirror characteristics of the image formed by a plane mirror

  1. Real & inverted

  2. Real & erect

  3. Virtual & erect

  4. Virtual & inverted

Show answer
Correct Option: D
Explanation:

The image that is formed by a plane mirror will be virtual, upright, same size and inverted

The object distance and the image distance will be equal.

Thus, the image formed by a plane mirror is virtual and inverted.

Image formed by a plane mirror is
a) of same size as that of object
b) at the same distance behind the mirror as the object in front
c) erect, virtual
Mark the correct statements:

evs reflection of light by plane surfaces characteristics of an image formed by a plane mirror formation of image in a plane mirror characteristics of the image formed by a plane mirror

  1. a and b

  2. b and c

  3. a and c

  4. All

Show answer
Correct Option: D
Explanation:

Image formed by a plane mirror is of same size as that of object and is formed at the same distance behind the mirror as object is in front of the mirror.

And the image formed is virtual, erect and laterally inverted.

Answer-(D)

A plane mirror is made up of:

physics light, shadows and reflections characteristics of an image formed by a plane mirror formation of image in a plane mirror characteristics of the image formed by a plane mirror

  1. a few metre thick glass plate

  2. a few mm thick glass plate

  3. a few cm thick glass plate

  4. none of these

Show answer
Correct Option: B
Explanation:

A plane mirror is made from a few mm thick glass plate. The front part is highly polished and the back part is silvered.

When the distance between the object and the plane mirror increases :

evs light, shadows and reflections characteristics of an image formed by a plane mirror formation of image in a plane mirror characteristics of the image formed by a plane mirror

  1. The image remains same

  2. The size of the image will become less than the size of the object.

  3. The distance between the image and the plane mirror increases

  4. The distance between the image and the plane mirror decreases

Show answer
Correct Option: C
Explanation:

When the distance between the object and the plane mirror increases because the distance between the image and the plane mirror increases.

Which of the following are the properties of plane mirror images?

evs light, shadows and reflections characteristics of an image formed by a plane mirror formation of image in a plane mirror characteristics of the image formed by a plane mirror

  1. The image is the same size as the object

  2. The image is virtual

  3. The image is inverted

  4. Image distance is equal to object distance

Show answer
Correct Option: A,B,D
Explanation:

In case of a plane mirror, image is virtual, erect, same size as the object and image distance is equal to object distance.

A point object is placed midway between two plane mirrors a distance apart. The plane mirrors form an infinite number of images due to multiple reflections. The distance between nth order images formed in the two mirrors is
