Final answer:
The safe distance for the green lantern depends on factors such as the power of the lantern and the intensity of the light.
Step-by-step explanation:
In physics, the concept of a safe distance is often associated with different situations and variables. In the case of the green lantern, the safe distance would depend on factors such as the power of the lantern, the intensity of the light, and the desired level of exposure. For example, if the green lantern emits a high-intensity light, a safe distance might be farther away to avoid potential eye damage. On the other hand, if the light is less intense, a closer distance might be considered safe.
