Predicting the speed of light

    1. The problem statement, all variables and given/known data

    I was wondering if anyone knew of an equation or table that I could compare my labs measured speed of light to? I'm aware that the index of refraction is 1.000293 at 1 atm and 0°c but was hoping to find a way to check our values specifically. We ended up with 1.0002343 so I know we were close.

    thanks for the help!

    You can play around with effects of wavelength, temperature and pressure (as well as humidity and carbon dioxide content) here.

    Perfect, thank you! That put us a bit closer to the index (I figured this was the case) and gives me a way to make quick comparison's for future experiments. Really appreciate it.
