If the temperature of the solar surface is 5800 K and Wien's law for the peak wavelength of the spectrum of the Sun, assumed to be a blackbody, is given by $\lambda$_max T = 2.9*10⁶, with T in Kelvins and $\lambda$ in nanometers (nm), what is the expected peak wavelength of light from the Sun?

Question

Quizplus · Accepted Answer

Wien's law states that the peak wavelength of the spectrum of a blackbody is inversely proportional to its temperature. The higher the temperature, the shorter the peak wavelength. The temperature of the solar surface is 5800 K, so the peak wavelength of light from the Sun is expected to be around 500 nm, which is in the visible light range.
