A body at a temperature of 6000 K radiates energy with an intensity, I, of 40 MW m−2.
(1) a i Show that the wavelength, λmax , at which the maximum intensity of radiated energy lies is about 480 nm.
(2) ii In which part of the electromagnetic spectrum does this wavelength lie?
(3) b Calculate the emissivity, ϵ , of the body.
