A convex mirror used as a rear-view mirror in a car has a radius of curvature of 3 m. If a bus is located at a distance of 5 m from this mirror, find the position of image. What is the nature of the image ?

An object placed 20 cm in front of a mirror is found to have an image 15 cm

(a) in front of it,

(b) behind the mirror.

Find the focal length of the mirror and the kind of mirror in each case.

An arrow 2.5cm high is placed at a distance of 25 cm from a diverging mirror of focal length 20 cm. Find the nature, position and size of the image formed.

A diverging mirror of radius of curvature 40 cm forms an image which is half the height of the object. Find the object and image positions.

The radius of curvature of a convex mirror used as a rear view mirror in a moving car is 2.0 m. A truck is coming from behind it at a distance of 3.5 m. Calculate

(a) position, and

(b) size, of the image relative to the size of the truck. What will be the nature of the image ?
