first of all, Im not quite sure, if I put this post in the correct topic, so sorry if that's the case.

The things is, altough I don't go to school anymore I recently stumbled upon some theories and wanted to check them myself using the formulas that I could find on the net. I also had to figure out the theory behind all that myself, so I would really be glad if someone could "check" on my research or correct it if I simply misunderstood a big part of it.

As far as I figured some guy named Max Planck formulated a theory in which he states that certain materials would absorb some specific amount of energy/light according to the wavelenght(s). Also that there are specific wavelenghts for each material which only can be absorbed. So if there's a meterial that could absorb wavelenghts of 2.8 x 10^-5, 4.5 x 10^-5 and 15 x 10^-5 meters of lenght, that would mean, that every other lightradiation would simply pass by not affecting the material at all (?).

Further I came accross the Displacement Law by Wien. which gives a formula to calculate the temperature of that specific wavelenght. (Lmax= b/T). So would that also mean that if there's a black body which is radiating a temperature of 10 degrees celsius, that this temperature would have a weavelenght of 1.101 x 10^-5 Meters (since b/-263.15 K= 1.101x10^-5 m)

thus making it impossible for the above material to absorb any of the energy?

or did I make some major mistake in my calculations or did I simply make some major faults using the wrong formulae etc.?

I'd be really thankful for your help, even if I'm not a physician or anything like that.

Greetings
