Question
A technician performs an experiment on a glass slap and finds that the critical angle for total internal reflection at the glass (refractive index n1) air (refractive index n2 = 1) interface is 43 +/- 2 deg. Find n1 and the associated error.
Answers
Slap or slab?
Solve
n1*sin43 = n2 sin90
n1 = 1/sin43
For the associated error, use the same formula with angles of 41 and 45 degrees.
