Answer:

POWER OF LENS :

Power of a lens

If a lens has a shorter focal length it is said to be more powerful. The power of a lens is defined as the reciprocal of the focal length. Lens power is measured in dioptres (D).

If the power of the lens is 6D find the focal length?

+6D since the power is positive, the lens is a convex lens. The focal length f = 1/p = 1/6 = 0.16 m.
