When an object is kept at any distance in front of a concave lens, the image formed is always:

When an object is placed at any finite distance from a concave lens, the image is formed…………….. .

Choose the correct alternative and write it along with its alloted alphabet: When an object is placed at any finite distance from a concave lens, the image is formed…….

Prove that when an object is placed in front of a concave lens, the image formed is (i) virtual (ii) erect (iii) diminished (iv) and located between pole and focus.

Prove that when an object is placed in front of a concave lens, the image formed is (i) virtual (ii) erect (iii) diminished (iv) and located between pole and focus.

When an object is placed at a distance 6 cm from a concave lens a virtual image is formed at a distance 4cm from it. Find the focal length of the lens.

An object is kept at a distance of 16 cm from a thin lens and the image formed is real. If the object is kept at a distance of 6 cm from the lens, the image formed is virtual. If the sizes of the images formed are equal, the focal length of the lens will be
