In a greenhouse,electromagnetic energy in the form of visible light enters the glass panes and is absorbed and then reradiated.What happens to this reradiated electromagnetic radiation from within the greenhouse?
A)100% returns to the atmosphere.
B)It's partially blocked by glass.
C)It's transformed into ultraviolet upon striking the glass.
D)It's reflected as visible light upon striking the glass.

Quizplus · Accepted Answer

The reradiated electromagnetic radiation from within the greenhouse is partially blocked by the glass panes, which causes some of it to stay within the greenhouse and contribute to the greenhouse effect. This is why greenhouses can get much hotter than the surrounding air, as the absorbed and reradiated energy becomes trapped inside. Option A is incorrect as some of the reradiated energy is retained within the greenhouse. Option C is incorrect as the visible light is reradiated as visible light, and does not transform into ultraviolet upon striking the glass. Option D is also incorrect, as the visible light is not reflected back as visible light.
