Question

the power of a lense is -5 D . Name the type of lense Also calculate its focal length​

Answer 1

Answer:

Explanation:

Optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f.
