All solids above 1000 K begin to emit radiation in what range on the electromagnetic scale?

radio
infrared
visible Light
ultraviolet

Respuesta :

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.

Answer:

The correct answer is visible light.
