1. What will the NA of the fibre be if it's immersed in water?
Basically we know the NA = 0.30 and refractive index is 1.50 for the fibre's core.
2. Snell's law
3. My theory is that NA is the sine of the critical angle.
n1 = 1.5, n2 = 1.333
NA = sin (theta_crit) = sin...
Hi, I am an undergraduate student in computer science and is currently studying physics, specifically photonics. I was just wondering if somebody here could advice me some good links about this subject since the course litterature is not instructional at all and very difficult to understand...
