The blackbody radation emmitted from a furnace peaks at a wavelength of 1.9 x 10^-6 m (0.0000019 m). what is the temperature inside the furnace?

Respuesta :

Answer:

Temperature, T = 1542.10 K

Explanation:

It is given that,

The black body radiation emitted from a furnace peaks at a wavelength of, [tex]\lambda=1.9\times 10^{-6}\ m[/tex]

We need to find the temperature inside the furnace. The relationship between the temperature and the wavelength is given by Wein's law i.e.

[tex]\lambda\propto \dfrac{1}{T}[/tex]

or

[tex]\lambda=\dfrac{b}{T}[/tex]

b = Wein's displacement constant

[tex]\lambda=\dfrac{2.93\times 10^{-3}}{T}[/tex]

[tex]T=\dfrac{2.93\times 10^{-3}}{\lambda}[/tex]

[tex]T=\dfrac{2.93\times 10^{-3}}{1.9\times 10^{-6}\ m}[/tex]

T = 1542.10 K

So, the temperature inside the furnace is 1542.10 K. Hence, this is the required solution.
