The surface temperature of a star can be calculated using Wien's Law, which states that the peak wavelength (λ_max) is inversely proportional to the temperature (T) of the blackbody. The formula is λ_max * T = b, where b is Wien's constant (approximately 2.897 x 10^-3 m*K). For a peak wavelength of 480 nm (or 480 x 10^-9 m), the temperature is calculated as T = b / λ_max, resulting in approximately 6,040 K.
