Flat Mirror Properties and Image Formation

The video tutorial explains the properties of flat mirrors, focusing on the concept of focal length being infinite. It demonstrates how to draw ray diagrams to determine the location of images formed by flat mirrors. The tutorial also covers the calculation of image distance and magnification, highlighting that images in flat mirrors are virtual, upright, and the same size as the object.

What is the object distance from the mirror in the given problem setup?

• 100 cm

• 25 cm

• 75 cm

• 50 cm

What is the focal length of a flat mirror?

• 0

• 50 cm

• Infinity

• 100 cm

How do rays behave when they hit a flat mirror?

• They reflect back parallel to the normal

• They converge at a point

• They pass through the mirror

• They scatter in random directions

What type of image is formed by a flat mirror?

• Real

• Inverted

• Virtual

• Magnified

What is the formula used to calculate the image distance in mirrors?

• S' = s - F

• S' = SF + s

• S' = SF / (s - F)

• S' = s + F

What is the image distance for the object placed 50 cm from a flat mirror?

• 50 cm

• -50 cm

• 100 cm

• 0 cm

What is the magnification of the image formed by a flat mirror?

• 1

• 2

• 0.5

• 0

What does a magnification of 1 indicate about the image size?

• Image is not visible

• Image is twice the size of the object

• Image is half the size of the object

• Image is the same size as the object

What does a positive magnification value indicate about the image orientation?

• Inverted

• Upright

• Reduced

• Magnified

Where is the image located in relation to the flat mirror?

• Behind the mirror

• On the mirror surface

• Above the mirror

• In front of the mirror
