Question

1. We wish to obtain an erect image of an
object using a concave mirror of
focal length 10 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.
​

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 size of the image will be larger than object.
