Final answer:
When a light source is close to an object, it creates darker shadows with crisp edges compared to larger light sources, which produce softer shadows with blurry edges.
Explanation:
When a light source, such as a candle, is close to an object, it produces darker shadows with crisp edges. This occurs because the smaller light source emits light rays that are more parallel, resulting in well-defined shadow edges. In contrast, larger light sources like long fluorescent bulbs create softer shadows with blurry edges due to the diverging light rays spreading out.
