Question

class 10 q1. We wish to obtain an erect image of an object using concave mirror of focal length 15 cm. What
should be the range of distance of the object from the mirror? Draw the ray diagram ​

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. The size of the image will be larger than object. Ray diagram is attached as image to the question
