Question

We wish to obtain erect image of an object using a concave mirror of focal length 15cm. What should be 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. Please answer this fastly

Answer 1

focal length of concave mirror = 15cm
object should be place in front of given concave mirror at a distance less than 15cm
image formed is virtual and erect
image size is larger than object

hope it helped u dear
thanks
mark it as brainliest answer

Answer 2

Explanation:

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.
