Question

To obtain an erect image of an object, a concave mirror of focal length 10 cm is used.

a) What should be the range of distance of an object placed in front of the mirror?

b) Where will be the image of the object if it is placed 25 cm in front of the mirror.

Draw the ray diagram for this situation.​

Answer 1

Answer:

Object distance should be less than the focal length for the formation of an erect image. Hence, the range of distance of object from the mirror should be less than 15 cm i.e. from 0 to 15 cm in the front of mirror from the pole. The nature of image so formed will be virtual and erect.
