The object \(y\) is projected
using a lens with foci at \(F\)
and \(F'\).
The focal length of the lens (the distance from the focus to the lens)
\(f = 20\, \mathrm{cm}\). The distance from the
object \(y\) to the lens
\(a = 60\, \mathrm{cm}\). Find the distance from
the lens to the image \(y'\).
\(30\, \mathrm{cm}\)
\(600\, \mathrm{cm}\)
\(\frac{20}
{3} \, \mathrm{cm}\)
\(25\, \mathrm{cm}\)
