I guess I didn't explain my attempt very well. I was trying to treat the problem with Snell's Law twice; once for the beam entering the fiber from the air, and a second time for refracting in the fiber such that the second angle of incidence is the critical angle, guaranteeing full reflection of...

Homework Statement Given a "new type" of optical fiber (index of refraction n = 1.23), a laser beam is incident on the flat end of a straight fiber in air. Assume nair = 1.00. What is the maximum angle of incidence Ø1 if the beam is not to escape from the fiber? (See attached file for...
