if a certain star emits radiation that has a peak wavelength of 421 nm, the temperature of the star is ______.
use wiens law with temperature = 3000000/wavelength

Explanation:

Step1: Identify given values

Wavelength = 421 nm = 421×10⁻⁹ m

Step2: Apply Wien's law formula

Temperature = $\frac{3000000}{\text{wavelength}}$ = $\frac{3000000}{421\times 10^{- 9}}$ K

Step3: Calculate the temperature

Temperature = $\frac{3000000}{421\times 10^{-9}}\approx7126\times10^{3}$ K = 7126000 K

Answer:

7126000 K
