State three observable phenomena where a particle behaves like waves. State the scientific principle underlying the operation of fibre optics.
(b) Explain each of the following terms as used in fibre optics: (i) core; (ii) cladding
Verified Correct Answer: .
Physical Principles & Numerical Solution
Observable phenomena when a particle behaves like Waves: (a) Diffraction: (b) Interference: (c) Compton effect: (d) Polarization: (e) Refraction (f) Reflection.
(b) (i) Core: The inner glass center where light travels. It has a high refractive index to keep the signal contained.
(ii) Cladding: The outer layer surrounding the core. It has a lower refractive index to reflect light back into the core, preventing signal loss.
