Vedclass · Answer

(B) The glass sheet acts as a transparent cover that allows short-wavelength infrared radiation from the sun to enter the solar heating device. Once inside,this radiation is absorbed by the internal components,which then re-emit it as long-wavelength infrared radiation. The glass sheet is opaque to these long-wavelength rays,preventing them from escaping. This phenomenon is known as the greenhouse effect,which helps in trapping heat inside the device.
