Question

The equation that relates the temperature of an object to the wavelength of its peak radiation is called _____.

the blackbody law
Wien's law
Kepler's law
the spectral law

Answer 1

The correct choice is

Wien's law

Step-by-step explanation:

According to Wien's law, wavelength of maximum intensity of emission of black body radiation is inversely proportional to absolute temperature (T) of the black body. The formula for the law is given as

`\lambda _(m)\propto (1)/(T)\\`

`\lambda _(m)=  (b)/(T)\\`

where

`\lambda _(m)` = wavelength of maximum intensity

T = temperature

b = Wien's constant

Answer 2

The equation that relates the temperature of an object to the wavelength of its peak radiation is called Wien's law. Wien's law states that: the black body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature.
