Answer:
T = 206 K
Explanation:
As we know by Wein's law of displacement that if we draw all radiations intensity with all possible wavelengths radiated from the object then the wavelength corresponding to maximum intensity of radiation is inversely dependent to the absolute temperature of the object.
So here we can say
[tex]\lambda = \frac{b}{T}[/tex]
here we know
b = Wein's constant
[tex]b = 2.89 \times 10^{-3}[/tex]
now we have
[tex]\lambda = 14000 nm[/tex]
from above equation
[tex]14000 \times 10^{-9} = \frac{2.89 \times 10^{-3}}{T}[/tex]
[tex]T = 206 K[/tex]
