I am preparing for a test. I really need help with this is problem. I uploaded a picture for the figure.
The figure below shows the path of a beam of light through several layers (n1 = 1.58, n2 = 1.39, n3 = 1.21 and n4 = 1.00) of different indices of refraction.
What must the incident angle,
We have to use Snell's Law: which is n1sin=n2sin
The Attempt at a Solution
FOR PART 1: This is what I did:
I know N for 1 and 2. The angle is 29.1 as given. So....
For Part 2: I am clueless.
Please guide me.
