For a wave traveling from a medium with refractive index n1 to n2 with n2 > n1, the amplitude reflection coefficient is given by: r = (n2 - n1)/(n2 + n1) Consider a beam of light passing through a single pane of glass. There is a reflection at the front surface of the pane, with the...

I'm afraid I'm having a bit of trouble understanding your last post chiro. I can't say that I've seen a lot of null/alternative hypothesis statements before, but the ones I have seen haven't been quite as terse as simply stating an expected value for a statistic. Stating a statistic doesn't...

Hi Chiro and thank you for the prompt response! You're right in assuming that I haven't done much statistics before. This isn't a question from a book or other source; I'm performing an independent investigation at university. The goal of the experiment is as described: to quantify to what...

I am attempting to investigate to what quantitative degree a physical theory agrees with observations of the phenomena it predicts (specifically, Fraunhofer theory). I want to use the chi-squared test to produce some confidence levels in the measurements made in different sections of the...
