The total radiation emitted by a certain star is a factor 16 times that of a second star of equal size. Calculate the ratio between the temperatures of the star.
lamda x T = 2.90x10^-3
The Attempt at a Solution
16I = I
Therefore, Wiens Displacement law (above):
16I x T1 = I x T2
Where I is equal on both sides.
T2/T1 = 16
I'm not too sure on what equations to apply to this! Do I use just Wien's Displacement Law and put them together? Doesn't look right (not supplied with answers).
Or do I use the Stefan Boltzmann Law (I = oT^4)?
How do I know which law to use?
Any help is greatful!
