Spherical Mirrors starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Spherical 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.

A concave mirror has a focal length of -15 cm. What is its radius of curvature?
A convex mirror has a focal length of 25 cm. What is its radius of curvature?
A student places an object 10 cm in front of a concave mirror of focal length 15 cm. Where will the image be formed?
Define the principal axis of a spherical mirror.
Describe the image formed by a concave mirror when the object is placed at the focus.
Describe the nature of the image formed by a convex mirror for any position of the object.
