Black body chemistry
WebGeneral College Chemistry 1 8 Blackbody Radiation, Photoelectric Effect Electromagnetic radiation can be generated by exciting matter to higher energies, such as by heating it. The emitted light can be either continuous (incandescent sources like the sun) or discrete (from specific types of excited atoms). Continuous spectra often WebWhen a blackbody is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. This emission is called blackbody radiation. A room temperature blackbody appears black, as most of the energy it radiates is infra-red and cannot be perceived by the human eye.
