Which one of the following statements is true with regard to a greenhouse ?
- A. The shorter wavelength infrared radiations from the Sun can enter into the greenhouse while longer wavelength infrared radiations from the ground and the plants inside the greenhouse cannot pass back out through the glass. ✓
- B. The shorter wavelength infrared radiations from the Sun can enter into the greenhouse and the longer wavelength infrared radiations from the ground and the plants inside the greenhouse can also pass back out through the glass.
- C. The shorter wavelength infrared radiations from the Sun cannot enter into the greenhouse while longer wavelength infrared radiations from the ground and the plants inside the greenhouse can pass back out through the glass.
- D. No infrared radiation can pass through the glass of the greenhouse.
Correct Answer: A. The shorter wavelength infrared radiations from the Sun can enter into the greenhouse while longer wavelength infrared radiations from the ground and the plants inside the greenhouse cannot pass back out through the glass.
Explanation
Greenhouse glass is transparent to incoming short-wavelength solar radiation, allowing it to enter. However, it is opaque to the outgoing long-wavelength thermal (infrared) radiation emitted by the warmed objects inside, thereby trapping heat.
