Irradiance and the Electromagnetic Spectrum
Description:
Life on earth is dependent upon energy in the form of
electromagnetic radiation from the sun. Students calculate the
surface irradiance of the sun and earth using the Stefan-Boltzman
Law, and calculate peak emission wavelengths using the Wien
Displacement Law. They identify the "type" of peak emission energy
using an electromagnetic spectrum diagram. They describe the
relationship between the temperature of an object and the wavelength
of peak energy emission.
