|
Solution: Click For PDF Version The thin lens equation is
where
Therefore,
As the image distance is negative, in the sign convention it is in the V-side of the lens, and therefore is to the left of the lens. |
.
We have to find where the image is formed.
,
is the object distance,
is the image distance and f
is the focal length.
