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

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

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

What are four main uses of topography map

Alex17521 [72]

Topographic maps are a type of map that show the relief of an area using contour lines to highlight elevation changes. Topographic maps have multiple uses from individuals who go hiking and orienteering to higher level uses in the fields of mining or civil engineering. Other fields which use topographical maps are geologists or architects or engineers constructing large scale architectural projects.
