Question

what is the equation of quatume theory of radiation?????​

Answer 1

Edγ= ((8πhγ3)/c3 ) X (dγ)/(exp(hγ/kT)-1)

Answer 2

Here, E is the energy of each quantum in Joules, γ is the frequency of the radiations in s-1, h is known as Planck's constant (a fundamental constant), h=6.626X10-34 J s. Also, E=hcw, where w is known as wave number. W= (1/λ) m-1. From above two equations, it is evident that γ=c/λ=cw.
