9.) An object of height 5 cm is placed 15 cm away from a convex mirror of focal length 20 cm. Find out the location of the image and magnification produced. What happens to the image if the object is moved

farther from the mirror?

10) A candle 5 cm in size is places at 30 cm in front of a concave mirror of radius of curvature 40 cm. At

what distance from the mirror should a screen be placed in order to obtain a sharp image? Describe the

nature and size of the image. If the candle is moved towards the mirror, how would the screen have to

be moved?

11) An object 2 cm in size is placed 30 cm in front of a concave mirror of focal length 15 cm. At what

distance from the mirror should a screen be placed in order to obtain a sharp image? What will be the

nature and the size of the image fanned? Draw a ray diagram to show the formation of the image in this

case

12) (a) To construct a ray diagram, we use two light rays which are so chosen that it is easy to know their

directions after reflection from the mirror. List these two rays and state the path of these rays after

reflection. Use these rays to locate the image of an object placed between center of curvature and focus

of a concave mirror

(b) Draw a ray diagram to show the formation of image of an object placed between the pole and

principal focus of a concave mirror. How will the nature and size of the image formed change, if the

mirror is replaced by converging lens of same focal length?
