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


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






3. Interference in time






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






5. 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






6. Media of Pure Transverse Waves






7. A wave that moves along the medium.






8. The relationship between sound speed and medium temperature






9. The return of a wave from a surface.






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






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






12. The point of maximum amplitude on a standing wave






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






14. Speed = wavelength x frequency






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






16. Media for a mixture of transverse and longitudinal waves






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






18. The fixed points on a standing wave






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






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






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






22. Range of wavelengths humans can see






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






24. 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.






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






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






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






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






29. Range of frequencies Humans can hear






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






31. Speed of sound in air






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






33. Line perpendicular to a surface or boundary.






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






35. Another word for P wave: longitudinal seismic wave






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






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






38. The relationship between sound speed and medium density






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






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






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






42. The relationship between sound speed and medium elasticity






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






44. 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.






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