Question
The bright southern star Alpha Centauri radiates most strongly at about $500 \mathrm{nm}$. What is its temperature? How does this compare to the Sun's?
Step 1
Mathematically, this is given by: λ_max = b / T where λ_max is the peak wavelength, T is the temperature in Kelvin, and b is Wien's constant, approximately equal to 2.898 x 10^(-3) m*K. Show more…
