Question

Planck’s theoretical expression for the frequency distribution of blackbody radiation is R(ν) =[2πh/c2] [ν3/ehν/kT – 1]. By fitting experimental blackbody radiation curves using this equation, Planck not only obtained a value for h, but also obtained the first reasonably accurate values for k, NA and the proton charge e. Explain how Planck obtained values for these constants.

Answer 1

Ans-

the Black body radiation, the solar constant, the Planck's law and Wein's exists not only at zo but at every point z in some neighborhood.

First, we consider the properties of waves in a box and work out an expression for the radiation
spectrum in thermal equilibrium at temperature T.
