## Blackbody

Blackbody. Radiated electromagnetic energy is the source of radiated thermal energy. Depends on wavelength Objects can emit and absorb electromagnetic energy. Emission coefficient e l Absorption coefficient a l Expect a distribution I l that depends on temperature. Kirchhoff’s Radiation.

## Blackbody

Blackbody. A black body is an ideal system that absorbs all radiation incident on it The electromagnetic radiation emitted by a black body is called blackbody radiation. Stefan’s law. Wien’s displacement law λ max T = 2.898 x 10 -3 m.K.

“Blackbody Radiation”. Despite what textbooks say, energy is NOT quantized in BB Rad. Action is quantized [every photon has action 2( ħ/2)]. Energy is ħ , and all values of  occur at various intensities. Planck never accepted quantized light. He insisted that light was
