Distribution Of Energy In The Spectrum Of Black Body

Name the law which helps us to explain the distribution of energy in the spectrum of a black body for (i) short wavelength only (ii) long wavelength only.

State Stefan's law and Wien's displacement law. Draw graphs showing the distribution of energy in the spectrum of a black body. Explain what quantity is plotted against the wavelength . By considering how this energy distribution varies with tempaerature expalin the colour changes which occur when a piece of iron is heated from cold to near the melting point.

State Stefan's law. Sketch graphs showing the distribution of energy in the spectrum of black body radiation at three temperatures, and indicate which curve corresponds to the highest temperature.

The spectrum from a black body radiation is a

The spectrum from a black body radiation is a

In the figure, the distribution of energy density of the radiation emitted by a black body at a given temperature is shown. The possible temperature of the black body is
