The Ciddor equation relates the refractive index of air to the wavelength of light. A user is seeking the complete equation to calculate the second derivative for group velocity dispersion (GVD) but is unable to find it due to paywalls on relevant websites. Other participants in the discussion express unfamiliarity with the equation and suggest links, but the original poster has already reviewed those resources. The need for the full function remains unmet, highlighting a gap in accessible information. This discussion emphasizes the challenges of obtaining specific scientific equations without financial resources.

hi anyone here use the ciddor equation before?

supposedly there's an equation linking refractive index n of air to the wavelngth of light.

its an equation that i need, but for the life of me i cannot find it as its often on websites that you have to pay for and i have noi money.

would appreciate if someone could give it to me.

sorry, i ve seen that already.

thing is i need the full function so as to tke the second derivative to calculate the GVD
 

Thread 'Looking for info about the Sombrero Galaxy'

Hi, I saw someone with an avatar on a different forum that turns out to be the sombrero galaxy. AI says, too distant to know much about, aside from billions of starts, potentially tons of planets, and a supermassive black hole in the center. I find that setup fascinating, despite knowing close to nothing about the universe. So I ask: could anyone point me in the direction of, or provide information about this galaxy? I do not trust AI beyond general information, and I like to go pretty...
