Hi,
Can someone tell me how to find the incident and refractive angles when only the deviation angle is known?
For instance, I know that Snells law is n1 sin(i) = n2 sin(r)
I know that the materials are air (n1=1) and glass (n2=1.5)
And I know that the deviation angle d is 30deg.
I can summise that d = i  r
and r = arcsin( (n1/n2) x sin i )
therefore i = arcsin( (n1/n2) x sin i ) + d
How do I find i? Do I use an iterative method? How does that work?
Thanks in advance
