About this exercise type...The electromagnetic spectrum of emitted radiation depends on the _ of the source.
A theoretical object known as a blackbody is used to describe the properties of a perfect _ of radiation. It is defined as an object — _ — that at a _ temperature, absorbs all incoming radiation _ and has the _ possible emission in _ directions and at _ wavelengths.
Blackbody emission is described by _ Law. This law describes the _ of a blackbody at a particular _ as a function of the _ of the blackbody and the _ of the emitted radiation. In addition, the law also includes certain constants: _ constant, 6.62606876·10–34, which has the dimensions [_]; _ constant, 1.3806503·10–23, which has the dimensions [_] and the _, 2.99792458·108, which has the dimensions [_].
Blackbody radiation has a number of characteristics. There is _ dependence of radiated energy on wavelength: the _ the wavelength the higher the radiated energy. Emitted power _ with increasing temperature.
