    How to find the right material to change the wavelength of light?

    Hello all, I'm working on a personal design problem and am stuck. I am trying to figure out "how to figure out" what material I would need. I hope that makes sense.For example: I have light of 400nm and I want to change it to light of 500nm. I figured I could just pass the light through a...

    Thermodynamical fluctuations, mean square deviation help

    Homework Statement Recalling that k=R/Na (Na is Avogadro's number), show that the density of fluctuations of an ideal gas are given by : <(dp)^2> / p^2 = 1 / (N*Na) where p is the density (mass/V) That is, the relative mean square density deviation is the reciprocal of the number of...
