Wien's law can be used to find the wavelength at which the emission of a black body is at its maximum. The formula is λ_max = b / T, where b is Wien's constant (0.00290 m·K) and T is the temperature in Kelvin. Substituting the given values, λ_max = 0.00290 m·K / 6000 K = 0.000483 m, or 483 nm.

The Surface Temperature of the Star Is 6000 K
