    There's some missing information. The spectrum will follow Planck's Law, with maximum intensity at a wavelength defined by Wien's Law. You can but those temperatures into Wien's law to find where the max wavelength will be.

    lambda = (2.898*10^-3 m*K) / T where m is meters and T is temperature in Kelvin
