Default Rayleigh scattering question



Hello,

a mostly academic question, please (not for a homework assignment,
thankfully!). Suppose instead of the roughly 80% nitrogen/20% oxygen
atmosphere you had different gases--for fun use 80% argon and 20% xenon.
Would the resulting change in particle size change the Rayleigh scattering
such that the blue photons would be less predominant? Prince's "purple
sky", for starters?

Happy Father's Day, all!

Regards,
Dan

Default Rayleigh scattering question

Hello,

Actually, I was at that exact website when I came up with the question! I
was simply (emphasis on simply) thinking the sky's color may be variable
with different atmospheric
gaseous contents. As best I could tell the equations given just mention the
number of scatterers, and did not specify the size/composition of the
scattering atmospheric particles. So, are you saying the Rayleigh
scattering would the same, regardless of the atmosphere's composition?

Regards,
Dan

Dear Dan Beck:

I thought it was "purple rain"?

.... density, temperature, and shape.

.... page 3 "spectra of giant planets"

So it would be different. The initial scattering might not be
different, and there would be less of it with gasses without
molecular bonding. But the later absorption would definately be
different.
