Support your answer with reason.

We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case.
No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be
The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object?
Which one of the following materials cannot be used to make a lens?
A concave mirror produces three times magnified (enlarged) real image of object placed at 10 cm in front of it. Where is the image located?
Why do we prefer a convex mirror as a rear-view mirror in vehicles?
Name the mirror that can give an erect and enlarged image of an object.
The radius of curvature of a spherical mirror is 20 cm. What is its focal length?
Define the principal focus of a concave mirror.
