Question

An object is placed 5 cm away from a lens of magnification 3.2.

How far away from the lens is the image formed?

Answer 1

16 cm

Step-by-step explanation:

Magnification (M)= v/u

where V = image distance from lens

u = object distance from lens

Given that the object is 5 cm away from the lens

The magnification of the lens is 3.2

image distance from lens (v) = magnification * object distance = 3.2 * 5 =16cm
