CSET Science: Optics And Waves I

Subjects : cset, science
Instructions:
  • Answer 45 questions in 15 minutes. 2 minutes extra for reading the instructions.
  • 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. Boundary in which the end of the wave medium is free to move in the transverse direction.






2. Range of wavelengths humans can see






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






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


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






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






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






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






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






10. The relationship between sound speed and medium elasticity






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. Interference in time






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






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






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






16. The fixed points on a standing wave






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






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






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






20. 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.






21. The relationship between sound speed and medium temperature






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






23. Line perpendicular to a surface or boundary.






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






25. The point of maximum amplitude on a standing wave






26. Media of Pure Transverse Waves






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






28. Speed = wavelength x frequency






29. The return of a wave from a surface.






30. Range of frequencies Humans can hear






31. Media for a mixture of transverse and longitudinal waves






32. Speed of sound in air






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






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






35. 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.






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






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






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






39. A wave that moves along the medium.






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






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






42. The relationship between sound speed and medium density






43. Another word for P wave: longitudinal seismic wave






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






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