Question

If the emitted infrared radiation from Pluto, has a wavelength of maximum intensity at 75,000 nm, what is the temperature of Pluto assuming it follows Wien’s law?

Answer 1

Answer:38.68 K

Step-by-step explanation:

Given

`\lambda =75000nm`

wien's displacement law result gives us the relation between temperature and wavelength like

`\lambda`
`* T`=2898

`75000* 10{-9}* T=2898* 10^(-6)`

T=38.64 K
