Answer:
4202.8985 K
Explanation:
Using Wien's displacement law which states that the temperature and the wavelength of the blackbody radiation are inversely proportional.
So,
λmax= b/T
Where,
λmax is the peak of wavelength [tex]6.90\times 10^{-7}\ m[/tex]
b is the Wien's displacement constant having value as [tex]2.9\times 10^{-3}\ m K[/tex]
T is the Absolute Temperature in Kelvin.s
So,
T = b/λmax = [tex]\frac{2.9\times 10^{-3}}{6.90\times 10^{-7}}[/tex] = 4202.8985 K
