Explain the meaning of the terms focus and focal length in case of a convex mirror, with the help of suitable ray diagram. 

Name the mirrors shown in Figure (a) and (b).

In each case (a) and (b), draw reflected rays for the given incident rays and mark focus by the symbol F.

Complete the following diagrams in Figure by drawing the reflected rays for the incident rays 1 and 2.

Complete the following diagrams shown in Fig. by drawing the reflected ray for each of the incident ray A and B.

State the two convenient rays that are chosen to construct the image by a spherical mirror for a given object? Explain your answer with the help of suitable ray diagrams. 

Figure shows a concave mirror with its pole at P, focus F and centre of curvature C. Draw ray diagram to show the formation of image of an object OA.

Figure shows a concave mirror with its pole at P, focus F and centre of curvature C. Draw ray diagram to show the formation of image of an object OA.

The diagram below in Figure, shows a convex mirror. C is its centre of curvature and F is its focus. (i) Draw two rays from A and hence locate the position of image of object OA. Label the image IB. (ii) State three characteristics of the image.

Draw a ray diagram to show the formation of image by a concave mirror for an object placed between its pole and focus. State three characteristics of the image.

Draw a ray diagram to show the formation of image by a concave mirror for the object beyond its centre of curvature. State three characteristics of the image.

Name the mirror which always produces an erect and virtual image. How is the size of image related to the size of object? 

For what position of object, the image formed by a concave mirror is magnified and erect?

State whether the image in part (a) is real or virtual? 

State the position of object for which the image formed by a concave mirror is of same size.

 Write two more characteristics of the image. 

What type of mirror can be used to obtain a real image of an object?

Does the mirror mentioned in part (b) form real image for all locations of the object? 

Discuss the position and nature of image formed by a concave mirror when an object is moved from infinity towards the pole of mirror. 

Discuss the position and nature of image formed by a convex mirror when an object is moved from infinity towards the pole of mirror.
