State two uses of a plane mirror.

List the uses of concave mirrors and convex mirrors.

A double convex lens ( R_(1)=R_(2)=10 cm ) having focal length equal to the focal length of a concave mirror. The radius of curvature of the concave mirror

The sun subtends an angle half a degree at the pole of a concave mirror which has a radius of curvature of 15 m. Then the size (diameter) of the image of sun formed by the concave mirror is

Define the principal focus of a concave mirror.

State two uses of a barometer.

To construct a ray diagram, we use two rays which are so chosen that it is easy to know their directions after reflection from the mirror. List two such rays and state the path of these rays after reflection in case of concave mirrors. Use these two rays and draw ray diagram to locate the image of an object placed between pole and focus of a concave mirror.

(a) Draw the ray diagram for the formation of image of an object by a convex mirror and use it (along with the sign convention) to derive the mirror formula. (b) Use the mirror formula to show that for an object, kept between the pole and focus of a concave mirror the image appears to be formed behind the mirror.

The focal length of a concave mirror is 50cm. Where an object be placed so that its image is two times and inverted
