Question
Suppose a star radiates most strongly at about $200 \mathrm{nm}$. How hot is it?
Step 1
Mathematically, this is represented as: 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…
