Question

A spherical mirror with the outer surface as the reflecting surface is called a _____________.

Answer 1

Convex Mirror:

1. The convex mirror is a part of a spherical mirror having its outer bulging surface as a reflecting surface.
2. This bulging out surface reflects light outwards and is not used to focus light.
3. These mirrors form a virtual image as the focal point $\left(F\right)$ and the centre of curvature $\left(2F\right)$ are imaginary points in the mirror that cannot be reached.
4. This results in the formation of images that cannot be projected on a screen as the image is inside the mirror.
5. The image looks smaller than the object from the distance but gets larger as the object gets closer to the mirror.

Hence, A spherical mirror with the outer surface as the reflecting surface is called a Convex Mirror.
