You are asked to decide whether a given mirror is concave, convex or plane, without touching it. What method would you adapt to ascertain this?

What difficulty a car driver will face, if he uses a concave mirror instead of a convex mirror to see the roadway behind him?

Show mathematically where the object should be place so that the size of the image will be equal to the size of the object in the case of a concave mirror. Give ray diagram.

When an object is moved from very long distance to the focus, in what way the nature and size of the image will be affected, in case of a concave mirror?

What do you mean by linear magnification? What are its limiting values for a convex mirror?

You have learned that plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstance? Explain.

A virtual image, we always say, cannot be caught on a screen. Yet when we 'see' a virtual image we are obviously bringing it on to the screen (i.e., the retina) of our eye. Is there a contradiction?

An object is placed $10 \mathrm{cm}$ in front of a concave mirror with a focal length of $15 \mathrm{cm}$. Find the image position and the magnification.

Describe the image produced by placing an object $30 \mathrm{cm}$ in front of a convex mirror having a focal length of $10 \mathrm{cm}$.
