The image distance is 59.2 cm and the image is real and small.

Image distance

The distance of the image formed by the convex or converging lens is determined by applying the following lens equation.

1/f = 1/u + 1/v

where;

  • f is the focal length = 34 cm
  • u is the object distance = 80 cm
  • v is the image distance = ?

1/v = 1/f - 1/u

1/v = 1/34 - 1/80

1/v = 0.0294 - 0.0125

1/v = 0.0169

v = 1/0.0169

v = 59.2 cm

Thus, the image distance is 59.2 cm and the image is real and small.
