[QUOTE="s3a, post: 4481753, member: 235803"] [b]"Where should a second hole be placed in order for the light [...]?"[/b] [h2]Homework Statement [/h2] The problem and the solution are attached as jpg files. (Given that the problem depends on the drawing, I think it's more convenient for the reader to view the text in the image as well.) [h2]Homework Equations[/h2] Snell's Law: ##n_1 sin θ_1 = n_2 sin θ_2## [h2]The Attempt at a Solution[/h2] In the TheSolution.jpg, I don't, mathematically, get how it can it say ##2.54 sin 48.6° = 1.0 sin θ_2## since that would mean that ##asin(2.54 sin(48.6°))## would not exist (but, I do get total internal reflection when thinking about it theoretically rather than mathematically). Also, how is the leftmost 11.4° angle (from the normal) found to be 11.4°? Any input would be greatly appreciated! [/QUOTE]
