What is magnifying power of a magnifying glass of power 12 dioptre?
Dioptre /4 =Power. Thus 12 /4 =3x magnification
Why convex lens of short focal length is preferred on magnifying glass?
The power of a lens is measured in dioptres which is the reciprocal of the focal length in metres. A 5-dioptre lens would allow you to see something at a distance of 20 cm, while a 20-dioptre lens would allow the object to be seen from 5 cm (2 inches) so it would be more effective as a magnifying glass. Your arms are short.
