Homework Statement
This is from a old exam[/B]
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 ?
Homework Equations
n =c/v
The Attempt at a Solution
What are they asking for ? It is how the < changes during dry/humid days ?
