A black-body receives all radiation on its surface and discharges radiation based on its temperature. The characteristics of blackbody radiation can be described in terms of several laws: 1. Calculate the energy density of black body radiation from the Stefan-Boltzmann constant, emissivity and the temperature. A blackbody is an idealized volume which emits and absorbs the maximum possible amount of radiation at a given temperature in all directions over a wide range of wavelengths. The Wien's equation is given below: When plotted, it gives the following hyperbola: By Steven Holzner . Instructions; Please be aware that SpectraPlot may not use or have registered some of the aforementioned marks in other countries. A. SpectraPlot was conceived and built by 4 PhDs who specialize in ultra-violet, near- and mid-infrared spectroscopic gas sensing and imaging techniques: Prof. Mitchell Spearrin of UCLA, Prof. Chris Goldenstein of Purdue, Dr. Christopher Strand at Stanford, and Dr. Victor Miller. The intensity I ( λ , T ) I ( λ , T ) of blackbody radiation depends on the wavelength λ λ of the emitted radiation and on the temperature T of the blackbody ( Figure 6.3 ). Planck's law describes the electromagnetic radiation emitted from a black body at a certain temperature. Intensity emitted in a unit of solid angle in the wavelength interval dλ can be conveniently defined as: I (λ, T) dλ. C is the optical beam chopper factor (C=0.5 in an ideal optical beam chopper), and W(λ) is the blackbody spectral density given by the following equation (i.e., the power radiated per unit wavelength interval at wavelength λ by a unit area of a blackbody at temperature T B). A green leaf absorbs almost all wavelengths except the green wavelength range between 500 nm and 550 nm. Blackbody radiation is emitted in the form of a spectrum, where intensity is a function of frequency or wavelength. A. Yep!
