Explanation:
The lens equation shows the relation among focal length of the lens, image distance and object distance. It can be expressed as:
=
+ 
where: f is the focal length of the lens,
is the object distance to the lens and
is the image distance to the lens.
The lens equation can be used to determine the unknown value among the variables f ,
and
.
