Multiple choice 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

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

  1. Real & inverted

  2. Real & erect

  3. Virtual & erect

  4. Virtual & inverted
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

  1. a and b

  2. b and c

  3. a and c

  4. All
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

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

  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

C Correct answer
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?

  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
Reveal answer Fill a bubble to check yourself
A,B,D Correct answer
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

  1. $n a$
  2. $2 n a$
  3. $0.5 n a$
  4. ${ n }^{ 2 }a$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When an object is placed midway between two parallel mirrors separated by distance 'a', the images are formed at distances 0.5a, 1.5a, 2.5a, etc., from each mirror. The distance between the nth order images is 0.5na.
