Write true or false for the following statement:
Glass cover in a solar heating device allows the short wavelength of ultraviolet radiations to enter the solar cooker.

(FALSE) The statement is False.
Explanation: Glass is transparent to visible light and infrared radiation (heat),but it is opaque to ultraviolet $(UV)$ radiation. The glass cover of a solar cooker allows short-wavelength visible light to enter,which is then absorbed by the black interior and converted into heat (infrared radiation). This heat is trapped inside because glass does not allow long-wavelength infrared radiation to escape easily (the greenhouse effect). It does not allow $UV$ radiation to pass through.
