Questions Related to reflection at plane surface

Multiple choice physics reflection of light and shadow lateral inversion right or left reflection at plane surface

Mark correct option.

  1. The laws of reflection of light hold only for plane surfaces

  2. The size of virtual image can be measured by receiving it on screen

  3. Plane mirror alongs form an erect image

  4. Plane mirror may form inverted image
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Let solve it by each option

  1. Law of reflection of light holds good for all the mirrors irrespective of their shape and size, hence option A is false
  2.  A virtual image cannot be caught on screen so we cannot measure the size, it is also a false statement
  3. Plane mirror always forms a virtual image, hence it's a false statement
  4. Light rays  which comes from the object  get reflected from plane mirror and reaches to human eye, at this point human feel that reflected ray is coming from the mirror . This is the reason why object looks laterally inverted
  5. Hence option D is the right answer

Multiple choice evs magic with mirrors lateral inversion right or left reflection at plane surface

Lateral inversion is a feature of plane mirrors, in which:

  1. The top part of the object appears to be the bottom part of the image.

  2. The left side of the object appears to be the right side of the image.

  3. Image appears to be inverted upside down and also sideways.

  4. All of the above.

B Correct answer
Explanation
$ \bf{Lateral\ Inversion} $ is the phenomenon in which when looked through a mirror, the left-hand side of an object appears as right-hand side of the image and vice versa.

Hence, the correct answer is OPTION B.
Multiple choice evs magic with mirrors lateral inversion right or left reflection at plane surface

A boy in front of mirror throws ball from right hand and catches with left hand. The direction of image of ball as seen from image of boy is:

  1. Right hand to left hand

  2. Left hand to Right Hand

  3. Right hand to Right Hand

  4. Left Hand to Left Hand
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Due to lateral inversion of boy, left appears on right and right on left. 

Multiple choice evs magic with mirrors lateral inversion right or left reflection at plane surface

Why is it difficult to read from image of a book in plane mirror?

  1. Due to lateral inversion

  2. Due to scattering

  3. Due to vertical inversion

  4. Due to loss on reflection
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

On reflection, Objects undergo lateral inversion.

Most of the alphabets are not symmetrical laterally and on reflection produce unrecognizable alphabets. Also, letters on the right appear on the left. This hurt the sequence of letters and makes words and sentences meaningless.

Why is AMBULANCE written laterally inverted on an Ambulance van?

  1. It gathers more attention since it is laterally inverted.

  2. Vehicle in front sees a laterally inverted image and perceives it correctly, hence giving side to the ambulance van.

  3. Vehicle in front sees a virtually erect image and perceives it correctly, hence giving side to the ambulance van.

  4. None of the above.

B Correct answer
Explanation

Ambulance is usually in a hurry. In order to convey the vehicle in front that it is an ambulance, it is written laterally inverted. When the driver of the vehicle in front reads through the rear-view mirror, the Image of this inscription, through lateral inversion, form a right oriented image.

Multiple choice evs magic with mirrors lateral inversion right or left reflection at plane surface

Interchange of left and right sides of an object in a plane mirror is known as:

  1. reflection

  2. refraction

  3. lateral inversion

  4. all
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The interchange of the left and right sides in the image of the object in a plane mirror is known as lateral inversion. In our daily experience, while looking in a mirror, the pocket of the left appears to be on the right of the image is also an example of lateral inversion.
