The physical model of a blackbody at … Web6 Mar 2024 · (4) on the blackbody radiation page). There is a fairly good overall fit between the Sun’s irradiance and a blackbody spectrum, at least if you ignore the Fraunhofer absorption lines in the solar spectrum. The peak of the blackbody irradiance spectrum is at 501 nm for a temperature of 5782 K. dog stomp pad snowboard
