$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

● If the inner side of the spherical mirror is reflecting, it is called a concave mirror.

● If the outer side of the spherical mirror is reflecting, it is called a convex mirror.

Answer 2

Answer:

Difference between convex and concave mirrors:

If the inner side of the spherical mirror is reflecting, it is called a concave mirror. If the outer side of the spherical mirror is reflecting, it is called a convex mirror. Concave mirrors can form inverted and real images and also virtual and erect images.

The basic difference between concave and convex are as follows: Concave describes a shape that curves inwards. The sideview mirror of a car, which curves inwards, is a good example of a concave shape. Convex describes a shape that curves outwards.

The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc.

The other easier differences are as follows:

Concave Mirror Convex Mirror

(i) Concave or bent-in surface

is the reflecting surface (i) Outer bulging surface is the

reflecting surface

(ii) It is a converging mirror (ii) It is a diverging mirror

(iii)It has a real focus (iii) It has a virtual focus

(iv) Image may be real or virtual (iv) Image is always virtual
