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.
In this installment EagleLight's LED University explains what color temperature means. LED color temperature measures the color of an LED light bulb. It defines the amount of pure white, yellow, red and blue in a light. Another way to think of the color temperature is how 'warm' or 'cool' is the white LED light bulb. Color temperature is measured in degrees Kelvin and is a measure of the part of the color spectrum that is found in light. A simple way to think about this is to compare the light from the sun from sunrise to sunset.
