CSET Science: Optics And Waves I

Subjects : cset, science
Instructions:
  • Answer 45 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. An oscillation of electric and magnetic fields that may propagate through a vacuum or through a medium






2. The reflection of light primarily in one direction - as from a mirror.






3. The displacement of the medium at any given point is the sum of the displacements of each wave.






4. A transparent outer layer of the eye that covers the iris and pupil. The cornea acts like a lens.






5. The dark circular spot in the middle of the iris of the eye. The pupil admits light into the eye.






6. The change in direction of a propagating wave (light or sound) when passing from one medium to another






7. A wave in which the motion of particles in the medium is in the same direction as the motion of the wave.






8. The return of a wave from a surface.






9. A wave that moves along the medium.






10. Boundary in which the end of the wave medium is fixed: not free to move.






11. The smooth curved surface at the back of the eye - where the lens of the eye projects an image. It then converts the light to electrical impulses






12. The fixed points on a standing wave






13. Media of Pure Transverse Waves






14. Media for a mixture of transverse and longitudinal waves






15. Capable of resuming its former volume or shape after being deformed






16. A wave in which the motion of particles in the medium is at right angles to the motion of the wave itself.






17. Sin?1/sin?2 = v1/v2 = n2/n1

18. Another word for an S wave; transverse seismic wave.






19. A substance that is the means of transmission of a wave.






20. The conditions existing at a boundary - such as the boundary between two media.






21. Another word for P wave: longitudinal seismic wave






22. The separation of white light into component colors - as happens when white light passes through a prism.






23. Line perpendicular to a surface or boundary.






24. A wave that does not travel; the superposition of two waves traveling in opposite directions






25. The relationship between sound speed and medium elasticity






26. Speed = wavelength x frequency






27. The interaction of two or more waves that displace the medium in the same way. The overlap of the maximum displacement points in each wave creates a maximum total displacement.






28. Boundary in which the end of the wave medium is free to move in the transverse direction.






29. Range of frequencies Humans can hear






30. Speed of sound in air






31. The relationship between sound speed and medium density






32. The bottom or pit of a transverse wave or water wave.






33. Interference in time






34. The opposite of compression; the spreading out of particles in the medium of a longitudinal wave.






35. A wave that propagates through a medium as a result of some disturbance.






36. Reflection of light in many directions by a rough surface. Also called scattering.






37. The energy in a wave is proportional to the square of the amplitude






38. The relationship between sound speed and medium temperature






39. The peak or top of a transverse wave or water wave






40. The interaction of two or more waves that displace the medium in the opposite way. The overlap of a positive displacement in one wave and a negative displacement in another may temporarily result in no displacement at all.






41. Arriving or incoming. An incident ray of light may give rise to a reflected ray and a refracted ray.






42. The nerve that relays information from the eye to the brain.






43. Range of wavelengths humans can see






44. The angle of incidence is equal to the angle of reflection.






45. The point of maximum amplitude on a standing wave
