What is the critical angle for total internal reflection in plastic (polymethylmethacrylate) at an interface with air?
I believe the answer is 42.2^o. I need to see each step and formula to solve this question. Please assume I know nothing because this would be the correct assumption. :)
The critical angle for total internal reflection is given by the relation,
Sin theta = n2/n1
where n2 ...
