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. 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






2. The relationship between sound speed and medium elasticity






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






4. Range of frequencies Humans can hear






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






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






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






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


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






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






11. 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.






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






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






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






15. The relationship between sound speed and medium temperature






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






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






18. Range of wavelengths humans can see






19. The point of maximum amplitude on a standing wave






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






21. The fixed points on a standing wave






22. Another word for P wave: longitudinal seismic wave






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






24. Media of Pure Transverse Waves






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






26. Media for a mixture of transverse and longitudinal waves






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






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






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






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






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






32. Line perpendicular to a surface or boundary.






33. Interference in time






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






35. Speed of sound in air






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






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






38. Speed = wavelength x frequency






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






40. The return of a wave from a surface.






41. The relationship between sound speed and medium density






42. A wave that moves along the medium.






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






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