We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case.
Fill in the following blank with suitable word:
A concave mirror .......... rays of light whereas convex mirror ............ rays
