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 11
A person is standing in front of a plane mirror. If the person moves 1 m closer to the mirror, by how much does the distance between the person and their image change?
A person stands 3 m in front of a plane mirror. If the person moves 2 m away from the mirror, what is the new distance between the person and their image?
A plane mirror is placed on a wall. If you want to see your entire body, what is the minimum height at which the bottom edge of the mirror should be placed above the floor?
A ray of light is incident on a plane mirror at an angle of 45° to the mirror surface. What is the angle of reflection with respect to the normal?
A ray of light strikes a plane mirror at an angle of 30° to the normal. What is the angle between the incident ray and the reflected ray?
Describe the path of a light ray incident on a plane mirror at an angle of 60° to the normal.
Describe what is meant by the term 'virtual image' in the context of plane mirrors.
Explain what is meant by lateral inversion in the context of plane mirrors.
Explain why a plane mirror forms only virtual images and not real images.
Explain why the image in a plane mirror appears laterally inverted.
If a person is 1.8 m tall, what is the minimum length of a plane mirror required for the person to see their full image?
If a person stands 2 m in front of a plane mirror, how far is the image from the person?
If an object is placed 15 cm in front of a plane mirror, where is the image formed?
If the angle between the incident ray and the reflected ray is 90°, what is the angle of incidence?
If the plane mirror is rotated by 20°, by how much does the reflected ray rotate?
State the two laws of reflection.
The distance between an object and its image in a plane mirror is 10 cm. What is the distance of the object from the mirror?
