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
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.
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?
