A) \[T={{\left( \frac{P}{A\,\varepsilon \,\sigma } \right)}^{4}}\]
B) \[T=\left( \frac{P}{A\,\varepsilon \,\sigma } \right)\]
C) \[T={{\left( \frac{A\,\varepsilon \,\sigma }{P} \right)}^{\frac{1}{4}}}\]
D) \[T={{\left( \frac{P}{A\,\varepsilon \,\sigma } \right)}^{\frac{1}{4}}}\]
Correct Answer: D
Solution :
Radiant power P is defined as energy radiated per unit area. ie, \[P=\frac{Q}{t}=A\varepsilon \sigma {{T}^{4}}\]\[\Rightarrow \] \[T={{\left( \frac{P}{A\varepsilon \sigma } \right)}^{1/4}}\]You need to login to perform this action.
