In anyother medium, rays travel at a slower speed, given byv = c/n n =refractive index of the medium.2. Rays travel straight paths, unless deflected by some change inmedium.3. If any power crosses the boundary, the transmitted ray directionis given by Snells law:n1 sin Øi = n2 sin Ør   Optical Principle(Internal reflection theory)  BSNL OF Comm&s OFC Faculty4 INCIDENT RAYS 1 REFLECTED RAYS REFRACTED RAYS113223N2 cladding¢r¢i (Principle of total internal reflection) n1 = 1.48n2 = 1.46N1 core
