Cal/cm2 for solar radiation

WebQuestion: Solar radiation falls on the earth at the rate of 1.94 cal/(cm^2 min) on a surface normal to the incoming rays. Assuming that the average wavelength of radiation is 5500 Angstroms, compute: a. the frequency of the radiation in 1/s. b. the wavenumber of the radiation in 1/cm c. the energy of a single photon of the radiation in Joules d. how … The solar constant (GSC) is a flux density measuring mean solar electromagnetic radiation (total solar irradiance) per unit area. It is measured on a surface perpendicular to the rays, one astronomical unit (au) from the Sun (roughly the distance from the Sun to the Earth). The solar constant includes radiation over the entire electromagnetic spectrum. It is measured by satellite as being 1.361 kilowatts per square meter (kW/m ) at solar minimum (the time in the 11-y…
