According to the National Funeral Directors Association, the median cost of a traditional funeral is approximately $7045. This includes the cost of embalming and a metal casket. The purchase of the gravesite and a burial vault or liner can add as much as $3000 more to the $7045 cost.
Brightness temperature is the temperature a black body in thermal equilibrium with its surroundings would have to be to duplicate the observed intensity of a grey body object at a frequency.This concept is extensively used in radio astronomy and planetary science.the Intensity or Brightness) is the amount of energy emitted per unit surface area per unit time per unit solid angle and in the frequency range between and; is the temperature of the black body; is Planck's constant; is frequency; is the speed of light; and is Boltzmann's constant.
The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source.n incandescent lamp 's light is thermal radiation, and the bulb approximates an ideal black-body radiator, so its color temperature is essentially the temperature of the filament. Thus a relatively low temperature emits a dull red and a high temperature emits the almost white of the traditional incandescent light bulb.
