Why are solar cookers covered by a glass plate?
Asked by | 16th Oct, 2010, 06:20: PM
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.
We hope that clarifies your doubt
