Another Explanation (5):
Using Wien's displacement law, λmax = b/T, where b is Wien's constant (0.288 cm·K) and T is the temperature in Kelvin.
First, convert the temperature to Kelvin: T = 3000°C + 273.15 = 3273.15 K
Then, calculate the wavelength:
λmax = 0.288 cm·K / 3273.15 K ≈ 8.79 x 10-4 cm ≈ 8.79 µm
