planck.zip: Planck radiation formula size 110 KB. This program calculates the radiated power, integrated between given upper and lower wavelength limits, by a Planck black body at given temperature. Units are degrees Kelvin, watts, and meters.

A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.Black-body radiation is distributed in energy (or frequency) in a manner set by the temperature T. A black b
