Answer» Solution :Blackbodyradiationcannot beexplainedby wave theoryof light .( Emitandabsorbwavefrequency and COLOUROF blackbodyradiationischangewithtemperature ) TheoryPlank suggestedthatatomsand moleculescouldemitand not isa continuousmannerPlankquantitiesnamequantumto thesmallestquantityofenergythatcan beemittedorabsorbed. Theenergy( E)or a QUANTUM of radiationisproportionalto itsfrequency( v ) and isexpressedby equation ( E `prop` v ) Important : WiththistheoryPlankwasable to explainthe DISTRIBUTION ofintensityin therediationfromblackbodyas afuntion offrequencyorwavelengthatdifferenttemperature . E= nhv(Eq. 2.11) wheren= 0,1,2 n=1 So E =HV =MINIMUM energy |
