List of top Physics Questions on Mirrors and Images asked in CBSE CLASS XII

A 5 cm long pencil is placed along the principal axis of a concave mirror of focal length 20 cm such that its nearest end is at a distance of 25 cm from the mirror. Calculate the length of the image of the pencil.
A 5 cm long pencil is placed along the principal axis of a concave mirror of focal length 20 cm such that its nearest end is at a distance of 25 cm from the mirror. Calculate the length of the image of the pencil.
If the silver coating around the centre of a concave mirror is removed, will the mirror still form the image of an object? Justify your answer.
Use the mirror formula to deduce that a convex mirror always produces a virtual image of an object kept in front of it.
Using the mirror equation and the formula of magnification, deduce that “the virtual image produced by a convex mirror is always diminished in size and is located between the pole and the focus.”
The magnification produced by a spherical mirror is \( -2.0 \). The mirror used and the nature of the image formed will be:
A concave mirror has a radius of curvature 20 cm. Calculate the distance of an object from the mirror so as to form an image of magnification -2. Also, find the location of the image.
Using Huygens’ principle, explain the refraction of a plane wavefront, propagating in air, at a plane interface between air and glass. Hence verify Snell’s law.
