Plane Mirrors starts at 7 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plane Mirrors. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 8

A person is standing 3 meters in front of a plane mirror. If the person moves 1 meter closer, what is the new distance between the person and their image?

A person stands 2 meters in front of a plane mirror. How far is the person from their image?

A ray of light strikes a plane mirror at an angle of 60° to the mirror surface. What is the angle of incidence?

Describe how the image of an object changes if the object is moved parallel to the surface of a plane mirror.

Describe the difference between a real image and a virtual image.

Describe what happens to the image if the object is moved closer to the plane mirror.

Explain why a plane mirror forms only virtual images.

Explain why letters appear reversed in a plane mirror.

If a ray of light strikes a plane mirror at an angle of 30° to the normal, what is the angle of reflection?

If an object is placed 15 cm in front of a plane mirror, where is the image formed?

If the angle of incidence is 45°, what is the angle between the incident ray and the reflected ray?

If you move 1 meter away from a plane mirror, how does the distance between you and your image change?

State the two laws of reflection.

The distance between the object and the plane mirror is 10 cm. What is the distance between the image and the mirror?

What does 'lateral inversion' mean in the context of plane mirrors?

What happens to the image if the plane mirror is rotated by 10° while keeping the object fixed?

What is a plane mirror?

What is the minimum height of a plane mirror required for a person of height 180 cm to see their full image?

A pencil is placed perpendicular to a plane mirror with its tip 8 cm from the mirror. If the pencil is 12 cm long, what is the distance between the tip of the pencil and its image?
