The light from the Sun is found to have a maximum intensity near the wavelength of 470 nm. Assuming the surface of the Sun as a black body, the temperature of the Sun is 6166 K. Explanation: Given: λm​= 470nm = 4.70$\times$10−7m b = 2.898$\times$10−3mK From Wien's displacement law, Tλm​ = b We get, temperature of sun T = b/(λ_m) $\therefore$ T = `(2.898 xx 10^(−3​))/(4.70 xx 10^(−7))` = 6166 K
