A 5 cm tall object is placed on the principal axis of convex lens of focal length 50 cm at a distance of 40 cm from it. Find the nature, position and size of the image.

An object is placed on the principal axis of concave mirror of focal length 10 cm at a distance of 8.0 cm from the pole. Find the position and the nature of the image.

An object is placed on the principal axis of concave mirror of focal length 10 cm at a distance of 8.0 cm from the pole. Find the position and the nature of the image.

An object is kept on the principal axis of a concave mirror of focal length 10cm, at a distance of 15 cm from its pole. The image formed by the mirror is:

An object is placed at a distance of 36 cm from a concave mirror of focal length 12 cm. Find the image distance.

An object is kept on the principal axis of a concave mirror of focal length 12 cm. If the object is at a distance of 18 cm from the mirror, calculate the image distance. Determine the nature of the image formed by calculating the magnification produced by the mirror.
