Document Summary

Characteristics of the energy emitted by a black body. Max = 2897 x 10-6 t where: max is the wavelength of maximum emission (m) T is the absolute temperature (k) (note: l is the greek letter lambda) the peak wave length changes as well, inversely related to the absolute temperature. Figure 2. 4 1st graph- max=0. 48 um (shortwave radiation) 2nd graph max=10. 2 um (long wave radiation) Photos 1st is reg. camera and the 2nd is an infrared camera-shows the energy he is emitting because we do not emit in the visible light spectrum. If we were to double the energy we would get entering. Reduction in intensity of the energy with distance from the sun: intensity reduces according to the square of the distance from the energy source (inverse square. Law: due to distance of 150 x 106 km between the earth and the sun, the earth only intercepts 0. 5 x. 10-9 of the sun "s energy output (half of one-billionth)
