To produce magnified erect image of a far object, we will be required along with a convex lens, is

A mirror produces magnified erect image of an object. The nature of the mirror is

A mirror produces a magnified erect image of an object. The nature of the mirror is

A virtual, erect and magnified image of an object is to be obtained with a convex lens. For this purpose, the object should be placed:

A virtual, erect and magnified image of an object is to be produced with a concave mirror of focal length 12 cm. Which of the following object distance should be chosen for this purpose?

The focal lengths of objective lens and eye lens of a Galilean telescope are respectively 30 cm and 3.0 cm. telescope produces virtual, erect image of an object situated far away from it at least distance of distinct vision from the eye lens. In this condition, the magnifying power of the Galilean telescope should be:

A convex lens of focal lengths 30 cm produces 5 times magnified real image of an object What is the object distance ?

A lens forms an erect, magnified and virtual image of an object. Draw a labelled ray diagram to show the image formation.
