Answer:
Infrared
Explanation:
Wien's displacement law states that the peak wavelength of the radiation emitted by an object is given by
[tex]\lambda=\frac{b}{T}[/tex]
where
[tex]b=2.898\cdot 10^{-3} m\cdot K[/tex] is the Wien's displacement constant
T is the absolute temperature of the object
In this problem,
T = 1000 K
So the peak wavelength of the radiation emitted by the body is
[tex]\lambda=\frac{2.898\cdot 10^{-3} m\cdot K}{1000 K}=2.90\cdot 10^{-6} m = 2.90 \mu m[/tex]
And this corresponds to infrared radiation, whose range of wavelength is 700 nm - 1 mm.
