This tutorial explains you how to calculate blackbody peak wavelength and temperature using wien's displacement law.
λ = Peak Wavelength b = 0.028977 mK (Wien's constant) T = Temperature
What wavelength (in nanometers) is the peak intensity of the light coming from a star whose surface temperature is 11,000 Kelvin?
temperature = 11,000 Kelvin.
Wavelength ( λ)
Let us find the value of Wavelength. Substitute the values in the formula,
|Wavelength (λ)||=||b / T|
|=||0.028977 mK / 11000 (b = 0.028977 mK)|
|=||0.000000263 * 1,000,000,000|
