Assertion:Real image of an erect object can never be erect.
Reason:Real image is formed due to intersectin of the rays infront of the mirror.

Form the image in case an object is moved from infinity to the concave mirror.

An object placed 12 cm from the pole of a concave mirror produces a real image magnified four times.Find the radius of curvature of the mirror.

Name a mirror which can give an erect and enlarged image of an object

We wish to obtain an erect image of an object, using a concave mirror of focal length 15cm 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 object? Draw a ray diagram to show the image formation in this case.

What is minimum distance between an object and the real image formed by a convex lens?

In Fig.2.56 ,the direct image formed by the lens(f=10cm) of an object placed of O and that formed after reflection from the spherical mirror are formed at same point.What is the radius of curvature of the mirror? .

The image obtained with a convex lens is erect and its lenth is four times the length of the object.If the focal length of the lens is 20 cm,calculate the object and image distance.

If a concave mirror of focal length f produces a real image n times the size of the object,then find the distance of the object from the mirror.
