HOw do you identify the angles?
OpenStudy (anonymous):
Here is an example I found over in the internet. A ray of light has an angle of incidence of 36.0 degrees on a block of quartz and an angle of refraction of 20.0 degrees. What is the index of refraction for the block of quartz? refractive index = sine(incident angle)/sine(refractive angle) =(sin 36)/(sin 20) =1.719 http://answers.yahoo.com/question/index?qid=20090110063902AAkwJoh And the next link is more info on it: http://webphysics.davidson.edu/faculty/dmb/edibleopticalmaterials/find_n_background.htm
