WebA blackbody is an ideal object, defined by researchers, which perfectly obeys the thermal radiation laws discussed in Section 1.3. Naturally, the emission and absorptivity of real surfaces are different. Fig. 1.8 shows a basic comparison between the surface emission and absorptivity of real bodies and blackbodies.

WebBlackbody 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 WebThe temperature of stars other than the Sun can be approximated using a similar means by treating the emitted energy as a black body radiation. So: = where L is the luminosity, σ is the Stefan–Boltzmann constant, R is the stellar radius and T is the effective temperature. This formula can then be rearranged to calculate the temperature:
