An object is placed at a distance of 7 cm from the pole of a concave mirror. The focal length of the mirror is 10 cm. What will be the nature of the image formed?
The focal length of the concave mirror, f = 10 cm. Since the object is placed at a distance of 7 cm from the pole, hence it is situated in between the pole and the focus. Hence, the image formed will be magnified, virtual and erect.
