Several optics/electromagnetics questions.

  1. Jan 1, 2008 #1
    Hello everybody,Im new here and I wondered if some of you can help.

    1.Im kind of confused regarding Alpha (some links attachedm,Wiki links for simplicity) ,Im confused Im not sure if they all talk about the same thing or not.

    Im currently doing a a project and we measure the absorption,trancmisence,conductivity and epsilno_R of materials and I want to cross check the Alpha with several theories.But now Im not sure that its the same Alpha.


    2.Anyone knows how to get c through a Beer - Lambert experiment? I have A and L , but Alpha and c are both variables.

    3.How can I measure Meu_R (permability)?

    Thanks in advance for your time reading and awnsering this.
