Emittance from an object

  1. Dec 8, 2016 #1
    1. The problem statement, all variables and given/known data

    Can anybody explain this picture?
    My guess is: the object emits every wave-length but it emits more wavelengths or more light from the colour that the peak is at. Is this correct? Why does the object emit wvery colour?

    2. Relevant equations

    3. The attempt at a solution

    I see no picture and the link takes me to a totally blank page.

    I've inserted a copy of the image to make it viewable without following a link.

    @Drizzy: Look up black body radiation or black body spectrum.

    I have read about it but no website has an answer to my question

    My guess is thatn objectsens out wavelengths that correspond to the light that makes the elctron excited. So if we have an object that can get excitet from every wavelength then it is going to sens out light with every wavelength
