Greenhouse effect: This effect results in the heating of enclosed spaces into which the sun shines through a transparent material such as glass or plastic. Visible light easily passes through the glass and is absorbed and reflected by materials within the enclosed space.
The light energy that is absorbed by dark pots and the dark absorber plate underneath the pots is converted into longer wavelength heat energy and radiates from the interior materials. Most of this radiant energy, because it is of a longer wavelength, cannot pass back out through the glass and is therefore trapped within the enclosed space.

When sunlight falls over the solar cooker top, the sun rays pass through the glass sheet cover and get absorbed inside the cooker box.
This glass sheet covers does not allow the solar energy to flow out in the form of radiant heat.Thus it traps more and more heat rays of the sun thereby producing green house effect.That is why glass lid is used in the solar cooker.

Glass covers function to trap the heta radiations inside the box.
Heat radiations once inside the box, will be absorbed by the content inside the box. The same radiations are reradiated in longer wavelengths, which fail to get refracted out of the glass cover.
Subsqeuently, the heat radiations get trapped inside the box & hence the temperature rise inside the box.

Solar means driven by sun-given energy or obtained from sunlight.
It needs to pass through a transparent surface.It can't pass through opaque or fully-translucent.
Glass, being a good transparent surface allows light energy to pass through it and thus, help in the functioning of the solar cookers.

When sunlight passes through the glass and hits the black coloured surfaces, the radiation is turned into heat, and the black surface also radiates out some of the energy, but it is in the infrared range. This infrared radiation cannot escape from the glass, so it continues to keep bouncing around, trapped.

the box of a?solar cooker covered?with a?glass plate.?glass?does allow the captured heat to go out and hence provide a greenhouse effect..?Solar cookers?are?covered?with a?glass plates?in order to capture heat. ... Just like the green house effect, the?glass plate?does not allow the heat to escape.
