Grade 8 - Image Formation Quiz

How is the size of the image formed by a plane mirror compared to the object?

• Larger

• Smaller

• The same

• Zero

In which direction is the image formed by a plane mirror oriented relative to the object?

• Upside down

• Sideways

• Same as the object

• Tilted

What type of image is formed by a plane mirror?

• Real and inverted

• Virtual and upright

• Real and upright

• Virtual and inverted

If a plane mirror is rotated by 90 degrees, what happens to the orientation of the image?

• It remains unchanged

• It rotates by 90 degrees

• It rotates by 180 degrees

• It becomes inverted

How does the distance of the image from the plane mirror compare to the distance of the object from the mirror?

• The image is closer to the mirror

• The image is farther from the mirror

• The image is at the same distance

• The distance cannot be compared

In a multiple reflection setup with two plane mirrors, how does the total number of images formed relate to the angle between the mirrors?

• It is always one more than the angle

• It is always two less than the angle

• It is twice the angle of inclination

• It depends on the angle between the mirrors

What happens to the number of images when the angle between two plane mirrors is 60 degrees?

• 5 images

• 6 images

• 3 images

• 2 images

How is the image formed by a plane mirror related to the object in terms of lateral inversion?

• The image is laterally inverted compared to the object

• The image is not laterally inverted

• The image is laterally magnified

• The image is laterally reduced

What effect does using more than two plane mirrors in a multiple reflection setup have on the number of images?

• It reduces the number of images

• It increases the number of images

• It has no effect on the number of images

• It makes the images appear distorted

What is the formula to calculate the number of images formed by two plane mirrors inclined at an angle θ?

• 360∘θ

• 360∘θ+1

• 360∘θ−1

• 180∘θ−1
