He says that Power net=EKA(T4-To4)
Where Power net= net power loss or gain through radiation
E- Emmisivity of a body
K- Stefans constant
A-Surface Area of the radiating body
T-Temperature of a body
T0- Temperature of the surrounding
And Power net=Power gained - Power loss
Now a question!
How can we say that heat gained by the body is also given by the emissivity of the body and its surface area while its the surrounding that's radiating to the body!
What I mean is, we where supposed to use the emissivity of the surrounding etc...
