Unformatted text preview: The type of light produced by an object will depend on its temperature, so let's digress slightly to investigate what ``temperature'' is. Temperature is a measure of the random motion (or energy) of a group of particles. Higher temperature (T) means more random motion (or energy). A natural scale would have zero motion at zero degrees (absolute zero). This scale is the Kelvin scale. It scales exactly like the Celsius system, but it is offset by 273 degrees. Here is a comparison of the Kelvin, Celsius, and Fahrenheit temperature scales: K C F-273-459 absolute zero 100-173-279.4 273 32 water freezes 310 37 98.6 human temperature 373 100 212 water boils (STP) 755 482 900 oven on ``clean'' setting 5840 5567 10053 Sun's temperature...
