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

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

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

Most of the land in russia could be described as

Sergio [31]

Answer:

A: Frozen taiga

Explanation:

Russia is the largest country in the world, and its land has several different characteristics. One of them though dominates by far, and that is the taiga, which is occupying more area than all of the other biomes in the country combined.

The taiga is stretching across all of the country from west to east, while the rest of the biomes are north and south of it. The land is covered with dense coniferous forests, representing the largest continuous forest in the whole world.

The taiga is not the most pleasant place for living though. The majority of the year is winter, and the temperatures are extremely cold, and in some parts of it they are as low as in Antarctica. There is lot of snowfall, usually several meters deep. The short summers are mild and very humid. Everything defrosts so big portion of the taiga is becoming marshy.
