Laser and Fiber Optics

4. the branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles, incorporating the concepts of quantization of energy, wave-particle duality, the uncertainty principle, and the correspondence principle.
5. (of a cable or line) consisting of two concentric conductors separated by an insulator.
8. subject to change
9. a compound that participates in a chemical reaction that produces another compound
10. A molecular beam is produced by allowing a gas at higher pressure to expand through a small orifice into a chamber at lower pressure to form a beam of particles moving at approximately equal velocities, with very few collisions between the particles.
12. Crossing of the Pacific Ocean
17. phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
18. a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
20. an electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction.
21. movement back and forth at a regular speed.
23. an expert in or student of physics.
24. an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light.

1. the natural or artificial growth of crystals on a crystalline substrate determining their orientation.
2. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
3. having or involving several or many layers.
5. a general agreement.
6. the branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits electromagnetic radiation.
7. communication over a distance by cable, telegraph, telephone, or broadcasting.
11. the process of converting data into radio waves by adding information to an electronic or optical carrier signal.
13. crossing of the Atlantic Ocean
14. materials which have a conductivity between conductors and nonconductors or insulators
15. the redistribution of atomic energy levels that takes place in a system so that laser or maser action can occur.
16. relating to the interrelation of electric currents or fields and magnetic fields.
19. belonging is naturally; essential.
22. a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
