Radiation+by+Tara+and+Krystal

=Radiation= -a type of heat transfer that does not require matter to travel.

black road-good absorber and emitter of radiation. During the day, the road will heat up fast and cool down at night. sand- bad absorber and emitter. Sand heats up very slow during the day and cools down slow at night. stars- have different colors and the colors are different temperatures. The coolest is red and the warmest color is blue.
 * FIVE IMPORTANT FACTS...**
 * radiation is heat transfer by electromagnetic waves
 * all objects emit radiation due to their thermal properties or have some internal thermal energy
 * type of radiation an object emits depends on its temperature
 * good absorbers and reflectors effect most of the radiation that hits the object
 * some objects emit mostly visible light,some ultraviolet, and some infrared
