The diagram shows a thin converging lens with principal focuses at ${F_1}$and ${F_2}$.
A small light source is placed at ${F_1}$. A beam of light from the source passes through the lens.
Which statement correctly describes the beam of light emerging from the lens?
1 )
The beam converges to ${F_1}$.
2 )
The beam converges to a point to the right of ${F_2}$.
3 )
The beam diverges from a point to the left of ${F_1}$.
The beam travels parallel to the principal axis.
