Vedclass · Answer

(C) The quantity $h 
u / K_{B}$ is related to the characteristic temperature of a system. According to the kinetic theory of gases,the average kinetic energy of a gas molecule is given by $\frac{3}{2} K_{B} T$. Equating the energy of a photon or quantum of energy $h 
u$ to the thermal energy $K_{B} T$,we get $h 
u = K_{B} T$. Thus,$\frac{h 
u}{K_{B}} = T$. Therefore,the quantity $\frac{h 
u}{K_{B}}$ has the dimensions of temperature. Hence,option $C$ is correct.

The quantity $h \nu / K_{B}$ corresponds to
