Find the size, nature and position of image formed when an object of size lcm is
placed at a distance of 15cm from a concave mirror of focal length 10cm?
An object 2cm high is placed at a distance of 16cm from a concave mirror which
produces a real image 3cm high:
a) What is the focal length of the mirror?
b) Find the position of the image?
A dentist mirror has a radius of curvature of 3cm. How far must it be placed from a
small dental cavity to give a virtual image of the cavity that is magnified 5 times?
A diverging mirror of radius of curvature 40cm forms an image which is half the
height of the object. Find the object and image position?
A rear view mirror used in a bus has a radius of curvature 3.5 m. If the driver of the
bus locates a car at 10.0m behind the bus, find the position, nature and size of the
image of the car.
An object 4cm high is placed at a distance of 6 cm in front of a concave mirror of
focal length 12 cm. Find the position, nature and size of the image formed.
How far an object should be placed from the pole of a concave mirror of focal length
20cm to form a real image whose size is 1/5 the size of the object.

10.0 cm. Find the distance from the mirror at which a screen should be placed in order
to obtain a sharp image. What will be the size and nature of the image formed?
The radius of curvature of a convex mirror used on a moving automobile is 2.0 m. A
truck is coming behind it at a constant distance of 3.5 m. Calculate (i) the position and
(ii) the size of the image relative to the size of the truck. What will be the nature of the
image?

you expect in the focal length of either?
A girl in the mirror finds her face appearing highly magnified, lower portion of the
body of the same size but laterally inverted and middle portion of the body highly
diminished in size. Guess the design of the mirror.
