A parallel beam of light is incident on a thin converging lens. F is one focal point of the lens. Which ray diagram shows the light after it has passed through the lens?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Aray diagram showing parallel incident rays diverging after passing through the lens, with their extensions passing through a point F on the principal axis.
Bray diagram showing parallel incident rays converging after passing through the lens, to a point on the principal axis that is not F.
Cray diagram showing parallel incident rays converging after passing through the lens, and passing through the focal point F on the principal axis.
Dray diagram showing parallel incident rays converging after passing through the lens, with their extensions passing through a point F on the principal axis.
✓ Correct answer
C: ray diagram showing parallel incident rays converging after passing through the lens, and passing through the focal point F on the principal axis.
