Black body is now called ideal or cavity\u00a0radiator and black body radiation is
cavity radiation; Stefan\u2019s law is now\u00a0known as Stefan Boltzmann law as\u00a0 Boltzmann derived it theoretically. There\u00a0is multiplicity of technical terms related\u00a0to thermal radiation – radiant intensity I(T) for total radiant power (energy\u00a0radiated\/second) per unit area of the\u00a0surface, in W\/m2 <\/sup>, I (T) =\u03c3 T4<\/sup>
; dimension and SI unit of \u03c3. For practical radiators I =\u2208. \u03c3 T4<\/sup> where \u2208 (dimension less) is called emissivity of the surface material; \u2208=1 for ideal radiators. The Spectral radiancy R(\u03bb). I (T)= \u222b R(\u03bb)d\u03bb.
Graph of R(\u03bb) vs \u03bb for different\u00a0temperatures. Area under the graph is I(T). The \u03bb corresponding to maximum\u00a0value of R is called \u03bbmax<\/sub>; decreases with increase in temperature.
Wien\u2019s displacement law; Stefan\u2019s law and Newton\u2019s law of cooling. [Deductions from Stefan\u2019s law not\u00a0necessary].<\/span>\u00a0 Greenhouse effect \u2013 self explanatory<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
