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






2. Range of frequencies Humans can hear






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






4. The relationship between sound speed and medium temperature






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






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






7. Line perpendicular to a surface or boundary.






8. The relationship between sound speed and medium density






9. Speed of sound in air






10. Another word for P wave: longitudinal seismic wave






11. The fixed points on a standing wave






12. Range of wavelengths humans can see






13. The point of maximum amplitude on a standing wave






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






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






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






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






18. The relationship between sound speed and medium elasticity






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






20. Speed = wavelength x frequency






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






22. A wave that moves along the medium.






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






24. The return of a wave from a surface.






25. 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.






26. Media of Pure Transverse Waves






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






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






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






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






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






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






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






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






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


36. Interference in time






37. Media for a mixture of transverse and longitudinal waves






38. 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






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






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






41. An oscillation of electric and magnetic fields that may propagate through a vacuum or through a medium






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






43. 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.






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






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