Light from a pointlike light source will enter a person's detector almost parallel if the source is very far away. If one moves closer to the source, the light entering one's detector
A) becomes more parallel.
B) becomes more divergent (the rays move away from each other).
C) becomes more convergent (the rays move toward each other).
D) remains unchanged.

Question

As one moves closer to a pointlike light source, the light rays entering the detector spread out more, becoming more divergent. This is because the angle subtended by the light source at the detector increases as the distance decreases, causing the light rays to diverge more as they enter the detector.
