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 12
A person 1.8 m tall stands in front of a plane mirror. What is the minimum length of the mirror required for the person to see their full image?
A person stands 2 m in front of a plane mirror. If the person moves 0.5 m closer to the mirror, by how much does the distance between the person and their image change?
A plane mirror is rotated by 10°. By how many degrees does the reflected ray rotate?
A ray of light is incident on a plane mirror at an angle of 45° to the normal. What is the angle between the incident and reflected rays?
A ray of light strikes a plane mirror at an angle of 60° with the mirror surface. What is the angle of reflection?
Describe how the image distance changes if the object is moved closer to a plane mirror.
Describe the characteristics of the image formed by a plane mirror.
Describe what is meant by lateral inversion in the context of plane mirrors.
Explain why the image in a plane mirror appears to be behind the mirror.
Explain why the image in a plane mirror is said to be virtual.
Explain why two plane mirrors placed at a right angle (90°) to each other can produce multiple images of an object placed between them.
If a person is standing 1.5 m in front of a plane mirror, how far is the image from the person?
If a person moves towards a plane mirror at a speed of 2 m/s, at what speed does the distance between the person and their image decrease?
If an object is placed 30 cm in front of a plane mirror, what is the distance between the object and its image?
If the angle between two plane mirrors is 60°, how many images of an object placed between them will be formed?
If the angle of incidence of a light ray on a plane mirror is 35°, what is the angle between the incident ray and the reflected ray?
State the law of reflection.
