In a concave lens, a ray of light emanating from the object parallel to the principal axis of the lens, after refraction:
- Apasses through the second principal focus.
- Bappears to diverge from the first principal focus.
- Cpasses through $2F$, which is the radius of curvature of the lens.
- Demerges parallel to the principal axis.
