Which of the following is not a property of the image formed by a plane mirror?

• Virtual

• Erect

• Laterally inverted

• Real

The distance between an object and its image formed by a plane mirror is 10 cm. What is the distance between the object and the mirror?

• 5 cm

• 10 cm

• 20 cm

• Cannot be determined

A person stands 2 meters away from a plane mirror. What is the distance between the person and their image?

• 2 meters

• 4 meters

• 1 meter

• Cannot be determined

If an object is placed 5 cm in front of a plane mirror, where is the image formed?

• 5 cm behind the mirror

• 10 cm behind the mirror

• 5 cm in front of the mirror

• At the same position as the object

A ray of light strikes a plane mirror at an angle of incidence of 30 degrees. What is the angle of reflection?

• 30 degrees

• 60 degrees

• 45 degrees

• 90 degrees

The image formed by a plane mirror is always:

• Real and inverted

• Virtual and erect

• Real and erect

• Virtual and inverted

If an object moves towards a plane mirror with a speed of 5 m/s, with what speed does the image move towards the object?

• 2.5 m/s

• 5 m/s

• 10 m/s

• 0 m/s

A tall object is placed in front of a plane mirror. The top of the object is 2 meters above the bottom of the object. What is the height of the image formed by the mirror?

• • 1 meter 

• • 2 meters 

• • 4 meters 

• • The height cannot be determined without knowing the distance to the mirror

• 45 degrees

• 90 degrees

• 0 degrees

• Cannot be determined without more information

A ray of light strikes a plane mirror perpendicularly. What is the angle of reflection?

• 0 degrees

• 30 degrees

• 45 degrees

• 90 degrees
