Greenhouse effect
Based on the order of the wavelength, ranging from the longest to the shortest, solar radiation is divided into three, namely infra-red (IR), visible light, and ultraviolet (UV). When sunlight on the glass of a greenhouse (green House) with short-wave radiation, namely visible light and UV can penetrate the glass, whereas the infrared reflected by the glass. The heat of short-wave radiation is absorbed by the soil and plants in the greenhouse, hopping hangars. Soil and warm plants we can classify as a cooler source of calories than the sun is very high temperature.
The greenhouse effect as an example, if you experience when the car is parked during the daytime sweltering under the sun with the windows tightly closed glass. When you get into the car in the afternoon when the sun was not shining. Then you will feel that the temperature inside the car is warmer than the air temperature outside the car.
