What is magnification of a lens?

The magnification of a lens is defined as the ratio of the height of an image to the height of an object.

The formula for magnification of a lens is given as;

M = v/u = hi/h

where;

  • v is image distance
  • u is object distance
  • hi is image height
  • h is object height

Under the same conditions, the height of a person whose film image is 16 mm is calculated as follows

M = 20 mm / 1.8 m = 16 mm/h

20 mm / 1.8 m = 16 mm/h

h = (16 mm / 20 mm) x 1.8 m

h = 1.44 m

Thus, under the same conditions, the height of a person whose film image is 16 mm is 1.44 m.
