Why placing a blue filter in front of a light source will give blue li

  1. Aug 26, 2009 #1
    It may be a very simple question.
    Why placing a blue filter in front of a light source will give blue light?Is this phenonmenon concerned with polarization of light(the vibration of electrons of the filter giving blue light)?
    Thanks very much!

    Re: filter

    No it has for sure nothing to do with polarisation, but I would say (the only reason that makes sense) that it's because of the allowed electronic transitions in the material or the allowed vibrations modes.
