How does the temperature of an object affect what wavelength of light it gives off? What kind of spectrum does this produce?

Answer 1

Are you familiar with Wien's displacement law?  A body whose peak radiative output occurs at wavelength λ_max will have an absolute temperature T given by 

 

λ_maxT = a,

 

where a is a constant.  You can also state the law as

 

λ_max = a/T.

 

Here you can see the relation between absolute temperature and peak wavelength.  This will produce a blackbody radiation spectrum.
