Difference between Concave and Convex Mirror

Q1

What are concave mirrors?

Concave mirrors are rounded or hollowed like the interior of a circle or sphere; they are also called converging mirrors.

Q2

What are convex mirrors?

Convex mirrors are rounded or curved like the exterior of a circle or sphere; they are called a fish eye or diverging mirror.

Q3

What is a mirror?

A mirror is a reflective surface that bounces off light, producing either a real image or a virtual image. When an object is placed in front of a mirror, the image of the same object is seen in the mirror.

Q4

Define the principal axis.

The imaginary line passing through the optical centre and the centre of curvature of any lens or a spherical mirror.

Q5

Define principal focus.

Principal Focus can also be called Focal Point. It’s on the axis of a mirror or lens wherein rays of light parallel to the axis converge or appear to converge after reflection or refraction.
