What is the formula for Wien's law used to estimate the surface temperature of a star?.
- A.T = 2.898 x 10^-3 / λ
- B.T = λ / 2.898 x 10^-3
- C.T = λ^2 / 2.898 x 10^-3
- D.T = 2.898 x 10^3 / λ
Model answer
What a good answer should say
- T = 2.898 x 10^-3 / λ
Explanation
Why this works
Wien's law states that the surface temperature (T) of a black body is inversely proportional to the wavelength (λ) at which the emission is maximized. This relationship is expressed as T = 2.898 x 10^-3 / λ, where λ is in meters.
