please help me out. details and explanations are very much appreciated. 

2. Figure 1 shows a cylindrical optical fiber, with length L and diameter D. held in water medium. A light source (laser, held inside the water) was incident towards the fiber at an angle 0,. It should be noted that this fiber does not contain cladding, and it can be assumed to just consisted of the core. (Note: other names for this kind of fiber would be "coreless fiber", which is ironic since the cladding and the core both being the same material, but with no notable border between them.) water laser L HD fiber Figure 1: Testing the optical fiber under water medium.
