What is Wien's law ?

Explanation

Wien's law states that the wavelength of maximum intensity of emission of a black body radiation is inversely proprtinal to the absolute temperature of the black body .
`lambda _(m) alpha .(1)/(T ) " ( or ) " lambda_(m) = (b)/(T)`
Where b is known as Wien's constant . Its value is `2.898 xx 10^(-3) m K`
