The image formed by a plane mirror is:

A concave mirror has a focal length of $10 \mathrm{cm}$. At which of the following distance should an object be placed so that it may form a virtual, erect and magnified image?

In a convex spherical mirror, reflection of light takes place at:

We wish to obtain an erect image of an object by using a concave mirror of focal length $10 \mathrm{cm}$. What should be the distance of the object from the concave mirror?

We wish to obtain an erect image of an object by using a concave mirror of focal length $10 \mathrm{cm}$. Is the image real or virtual?

We wish to obtain an erect image of an object by using a concave mirror of focal length $10 \mathrm{cm}$. Is the image larger or smaller than the object?

An object is placed at the following distances from a concave mirror of focal length $10 \mathrm{cm}$:

(a) $8 \mathrm{cm}$

(b) $15 \mathrm{cm}$

(c) $25 \mathrm{cm}$

Which position of the object will produce:

(i) a real image larger than the object?

(ii) a virtual image larger than the object?

(iii) a real image smaller than the object?

What kind of lens can form an inverted image larger than the object?
