A) \[W/{{(K)}^{4}}\]
B) \[eV/{{(K)}^{4}}\]
C) \[W/{{(m)}^{2}}{{(K)}^{4}}\]
D) \[eV/{{(m)}^{2}}{{(K)}^{4}}\]
Correct Answer: C
Solution :
\[E=\sigma At{{T}^{4}}\] \[\Rightarrow \] \[\sigma =-\frac{E}{At{{T}^{4}}}\] Unit of \[\sigma =\frac{1}{{{m}^{2}}s{{(K)}^{4}}}\] \[=\frac{W}{{{m}^{2}}{{K}^{4}}}\]
