Homework Statement[/B]I am supposed to fill out a table with the values of θi and θr with the given information of n1 being 1.00 and n2 being 1.50 for the first row, and I am not quite sure how to do that just knowing the values that were given. I am also supposed to find the sine of θi and θr, and stuff like that but I think once I figure out how to find those values that will be easy. Just doing a basic search on the internet, it seems cross multiplication will need to come into play somewhere here, if so, what should I cross multiply?
Homework Equations[/B]Snell's Law: n2/n1 = Sin θi/Sin θr
The Attempt at a Solution[/B]I have tried various things such as just doing n2/n1, but I just don't seem to be getting relevant answers, because I don't think I know how to apply the equation properly. I would appreciate it if anyone has any suggestions! Thanks :)
*Note: I have a scientific calculator if that would be of help
