Question

What is meant by ‘power of a lens’? ​

Answer 1

Answer:

1. 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).
2. Power of lens is known as the inverse of the focal length of the lens measured in meter(m). S.I unit of power = Dioptre (D) Power of lense = 1/ focal length in meter.
