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 10
A person is standing 3 m in front of a plane mirror. If the person moves 1 m away from the mirror, what is the new distance between the person and their image?
A person stands 2 m in front of a plane mirror. How far is the person from their image?
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 45°. What will be the angle between the incident ray and the reflected ray?
A person is standing 3 m in front of a plane mirror. If the person moves 1 m away from the mirror, what is the new distance between the person and their image?
A periscope uses two plane mirrors placed at 45° angles. Explain how the path of light changes as it travels through the periscope and how the image is formed.
A person is standing in front of two parallel plane mirrors facing each other. If the distance between the mirrors is 2 m, how many images of the person will be seen?
A plane mirror is placed vertically on a table. An object is placed 20 cm in front of the mirror. If the mirror is then moved 5 cm away from the object, what is the new distance between the object and its image?
