The image formed by a plane mirror is always ....... inverted.
- laterally
- virtually
- really
- none
Mark correct option.
- The laws of reflection of light hold only for plane surfaces
- The size of virtual image can be measured by receiving it on screen
- Plane mirror alongs form an erect image
- Plane mirror may form inverted image
The sideways reversal of the image by plane mirror is called :
- lateral inversion
- parallax
- optical illusion
- magic
Lateral inversion is a feature of plane mirrors, in which:
- The top part of the object appears to be the bottom part of the image.
- The left side of the object appears to be the right side of the image.
- Image appears to be inverted upside down and also sideways.
- All of the above.
An unlabeled analog clock is kept in front of mirror. Actual time on clock is 3. What is time in the mirror image?
- 3
- 9
- 6.15
- 9.30
A boy rotates his arm in clockwise direction in front of mirror. His mirror image rotates its arm in:
- anticlockwise direction
- clockwise direction
- oscillatory motion
- insufficient info
8OYATU in plane mirror appears as :
- 8OYATU
- 8OYatu
- UTAYO8
- 8oYATU
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:
- Right hand to left hand
- Left hand to Right Hand
- Right hand to Right Hand
- Left Hand to Left Hand
Why is it difficult to read from image of a book in plane mirror?
- Due to lateral inversion
- Due to scattering
- Due to vertical inversion
- Due to loss on reflection
Why is AMBULANCE written laterally inverted on an Ambulance van?
- It gathers more attention since it is laterally inverted.
- Vehicle in front sees a laterally inverted image and perceives it correctly, hence giving side to the ambulance van.
- Vehicle in front sees a virtually erect image and perceives it correctly, hence giving side to the ambulance van.
- None of the above.
Interchange of left and right sides of an object in a plane mirror is known as:
- reflection
- refraction
- lateral inversion
- all
Lateral inversion is generally seen in case of:
- convex mirror
- concave mirror
- plane mirror
- all of the above
In lateral inversion.
- Right side of the object will be right side of the image
- Left side of the object will be left side of the image
- Upside of the object will be down side of the object
- Right side of the object will be left side of the image
Two plane mirrors at an angle such that a ray incident on a mirror undergoes a total deviation of $240 ^ { \circ }$ after two reflections.
- the angle between the mirrors is $60 ^ { \circ }$
- the number of images formed by this system will be 5 , if an object is placed symmetrically between the mirrors.
- the no. of images will be 6 if an object is kept unsymmetrically between the mirrors.
- a ray will retrace its path after 2 successive reflections, if the angle of incidence on one mirror is $60 ^ { \circ }$ .
A clock fixed on a wall shows time $04:25:37$. What time will its image in a plane mirror show?
- $07:43:32$
- $07:43:32$
- $07:35:23$
- $43:27:36$
Which of the following letters will be seen with some change in a plane mirror?
- M
- T
- L
- W
In the image formed by a plane mirror, the left of the object appears on the right and the right appears on the left. This is called lateral inversion.
- True
- False
While standing in front of a plane mirror, if you touch your ............ ear with the right hand, it will be seen in the mirror that your right ear is touched with your ................ hand.
- Right, left
- Left, left
- Right, right
- Left, right
A clock fixed on a wall shows time 04 : 25 : 37. Its image in a plane mirror shows :
- 07 : 30 : 33
- 07 : 43 : 32
- 07 : 35 : 22
- 43 : 27 : 36
