Vedclass · Answer

(D) According to Prevost's theory of heat exchange,every body at all temperatures (above $T = 0 \ K$) continuously emits and absorbs thermal radiation.Since the human body temperature is approximately $37^{\circ}C$ $(310 \ K)$,it emits electromagnetic radiation corresponding to its temperature.According to Wien's displacement law,the wavelength of maximum emission for a body at $310 \ K$ falls in the infra-red region of the electromagnetic spectrum.Therefore,the radiation emitted by the human body is in the infra-red region.
