Spectroscopy Spectroscopy is the study of light as a function of wavelength that has been emitted, reflected or scattered from a solid, liquid, or gas. Absorption bands, the absorption and scattering processes of electromagnetic radiation and visible light —part of the electromagnetic...

you mean one like this? n^-1 = 1/n n^0 = 1 n^1 = n or n^0 =1

In this I agree and will be more careful in the future. If I find a better website I will post it here in case anyone is interested. I knew about Alfvén and did a web search, found his bio and an article by him, and linked to them. But note that the quotes and the link in my post are only...

Nereid: Thank you for your welcome to the PF. I think i will find very interesting reads in your forums. :smile: As you may have noticed I like the ideas Alfvén expresses in his article, but I am not a trained Physicist and I could not refute or confirm these ideas with scientific rigor...

Electricity in Space :cool: You may be referring to 1970 Nobel Prize in Physics winner Hannes Alfvén's 'magnetohydrodynamics'. He is usually regarded as the father of this branch of plasma physics. Here's a short biography: Hannes Alfven (1908-1995) In his own words from...
