If a blackbody is at 2000° C, what will be the peak wavelength emitted?
A) 1.67 $\mu$m
B) 1.28 $\mu$m
C) 0.679 $\mu$m
D) 1.45 $\mu$m

The peak wavelength emitted by a blackbody can be calculated using Wien's Displacement Law: λ_max = b/T, where b is Wien's constant (approximately 2898 μm·K). Converting 2000°C to Kelvin gives 2273 K. Using the formula, λ_max ≈ 2898 μm·K / 2273 K ≈ 1.275 μm. The closest option is 0.679 μm, which seems to be a mistake in the options provided.
