Which material property causes glass to give rise to the greenhouse effect in greenhouses!?
Glass has the property that allows certain wavelengths to pas through it (transmission) and others to be prevented from passing through (absorption and reflection) that produce the conditions experienced. The glass in a greenhouse allows short wave length infra-red radiation to pass through it and this radiation is absorbed by the materials inside the greenhouse. As a result of this, the materials inside heat up and then they in turn emit long wavelength radiation which is unable to pass through the glass, This radiation contributes to the greenhouse getting a bit warmer. The air in the greenhouse is heated mainly by contact with the warm materials inside the greenhouse. Since inside the greenhouse (with the doors closed,) there is hardly any convection to carry the heated air away and replace it by much colder air, the warmed air gets hotter and hotter. The long wave radiation absorbed by the glass only plays a very small part and the panes of the greenhouse remain cool to the touch e
