The radiosity of a black body is `M_(e) = 3.0W//cm^(2)`. Find the wavelength corresponding to the maximum emissive capacity of that body.

Explanation

From the radiosity we get the temperature of the black body. It is
`T = ((M_(e))/(sigma))^(1//4) = ((3.0 xx 10^(4))/(5.67 xx 10^(-8))) = 852.9 K`
Hence the wavelength corresponding to the maximum emissive capacity of the bosy is
`(b)/(T) = (0.29)/(852.9)cm = 3.4 xx 10^(-4) cm = 3.4 mu m`
