Refractive Index

  1. Jul 20, 2016 #1
    1. The problem statement, all variables and given/known data
    This is from a old exam

    Humid air has a different refractive index than dry air: in the microwave region n'(dry) > n'(humid) and n''(dry) < n''(humid), where n' and n'' denote the real and imaginary part of the refractive index, respectively. How are the effects asked for above different (qualitatively) on dry and humid days ?

    2. Relevant equations

    n =c/v

    3. The attempt at a solution

    What are they asking for ? It is how the < changes during dry/humid days ?

    It is asking for a qualitative answer. It is not asking for any solution to be worked out, but what does the real and imaginary parts mean. Hint: Read about the complex refractive index in the wikipedia article on refractive index.

    What ARE they asking for? The problem states "... the effects asked for above ..." so there must have been something "above"?
