Solution

Object placed at C :

A real, inverted image of the same size is formed at the centre of curvature
Image formed
A ‘B’ is at C the centre of curvature.
Size is equal to the size of object AB.
It is inverted and real.

State two positions in which a concave mirror produces a magnified image of a given object. List two differences between the two images.


To construct ray diagrams, two rays of light are generally so chosen that it is easy to determine their directions after reflection from a mirror. Choose two such rays and state the path/direction of these rays after reflection from a concave mirror. Use these two rays to find the position and nature of the image of an object placed at a distance of 8 cm from a concave mirror of focal length 12 cm.


If a concave mirror has a focal length of 10 cm, find the two positions where an object can be placed to give, in each case, an image twice the height of the object.


How can a concave mirror be used to obtain a virtual image of an object? Draw a diagram to illustrate your answer.


Answer the following question:
