Across
  1. 4. a region within a magnetic material which has uniform magnetization
  2. 6. the mirror-like reflection of light from a surface, in which light from a single incoming direction is reflected into a single outgoing direction
  3. 8. a dimensionless number that describes how light, or any other radiation, propagates through that medium
  4. 10. a wave that propagates as an oscillation of matter, and therefore transfers energy through a medium.
  5. 11. has light reflecting off of it
  6. 14. a wave vibrating at right angles to the direction of its propagation.
  7. 15. emits light
  8. 16. a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
  9. 17. the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection
  10. 19. the observation that many metals emit electrons when light shines upon them
  11. 23. the nucleus of an atom splits into smaller parts
  12. 24. the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
  13. 25. a sharp division, as of a population or group, into opposing factions
  14. 26. the degree to which a substance or device opposes the passage of an electric current
Down
  1. 1. a flow of electricity which results from the ordered directional movement of electrically charged particles.
  2. 2. the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h / mv
  3. 3. a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
  4. 5. the production of an electromotive force across a conductor when it is exposed to a varying magnetic field
  5. 7. a length or portion of time
  6. 9. the change in direction of a wave due to a change in its transmission medium.
  7. 12. a substance or device that does not readily conduct electricity.
  8. 13. the process or result of joining two or more things together to form a single entity
  9. 18. the force needed to extend or compress a spring by some distance is proportional to that distance
  10. 20. a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
  11. 21. is a variable force that gives rise to an equilibrium in a physical system
  12. 22. the rate at which something occurs or is repeated over a particular period of time or in a given sample.
