Using Wien’s Law, estimate the wavelength at which these common materials radiate their peak brightness (show your work):
SSSSS [86.1K]

Explanation:

Wien’s Law:

\lambda _{max}\propto \frac{1}{temperature}

The law states that the wavelength at which black body emits maximum heat  is inversely proportional to the temperature of the body in Kelvins.

\lambda _{max}=\frac{2.9\times 10^{-3}}{T}

1) Walls at 300 K

\lambda _{max}=\frac{2.9\times 10^{-3} mK}{300 K}

\lambda _{max}=9.666\times 10^{-6} m

2) Ice water at 273 K :

\lambda _{max}=\frac{2.9\times 10^{-3} mK}{273 K}

\lambda _{max}=1.062\times 10^{-5} m

3) Hot water at 373 K :

\lambda _{max}=\frac{2.9\times 10^{-3} mK}{373 K}

\lambda _{max}=7.775\times 10^{-6} m

4)Skin at 310 K:

\lambda _{max}=\frac{2.9\times 10^{-3} mK}{310 K}

\lambda _{max}=9.355\times 10^{-6} m

5)An incandescent light bulb at 3000 K

\lambda _{max}=\frac{2.9\times 10^{-3} mK}{3000 K}

\lambda _{max}=9.666\times 10^{-7} m
