A greenhouse is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.
The shorter wavelength infrared radiations from the sun can enter into the greenhouse, while longer wavelength infrared radiation from the ground and the plants inside the greenhouse cannot pass back out through the glass.
The shorter wavelength infrared radiations from the sun can enter into the greenhouse, while longer wavelength infrared radiation from the ground and the plants inside the greenhouse cannot pass back out through the glass.

Statement Analysis:
The question asks us to consider the given statements about a greenhouse and identify the correct ones. Let's analyze each statement:
Statement 1: The shorter wavelength infrared radiations from the sun can enter into the greenhouse.
This statement is correct. Shorter wavelength infrared radiation, also known as near-infrared radiation, can penetrate glass and enter the greenhouse. This is because glass is transparent to shorter wavelengths of infrared radiation.
Statement 2: Longer wavelength infrared radiation from the ground and the plants inside the greenhouse can pass back out completely through the glass.
This statement is correct. Longer wavelength infrared radiation, also known as far-infrared radiation, is absorbed by glass and then re-emitted. This means that the longer wavelength infrared radiation from the ground and the plants inside the greenhouse can pass back out through the glass, allowing for the greenhouse to be heated.
Statement 3: No infrared radiation can pass through the glass of the greenhouse.
This statement is incorrect. As discussed in the analysis of statements 1 and 2, both shorter and longer wavelength infrared radiation can pass through the glass of the greenhouse.
Correct Statements:
Based on the analysis above, the correct statements are:
- Statement 1: The shorter wavelength infrared radiations from the sun can enter into the greenhouse.
- Statement 2: Longer wavelength infrared radiation from the ground and the plants inside the greenhouse can pass back out completely through the glass.
Therefore, the correct answer is option B) 1 only.
