Wave Basic Concepts

Cards in this deck (42)

  1. 1What is the definition of a wave?A disturbance that CARRIES ENERGY without transferring matter
  2. 2The top of a wave is called what?CREST
  3. 3The bottom of a wave is called what?TROUGH
  4. 4The distance from one point on a wave to the same point on the next wave… often measured from crest to crestWAVELENGTH
  5. 5The height of the wave from the EQUILIBRIUM lineAMPLITUDE
  6. 6What is A?WAVELENGTHWhat is A?
  7. 7What is B?AMPLITUDEWhat is B?
  8. 8What is C?TROUGHWhat is C?
  9. 9What is D?CRESTWhat is D?
  10. 10What is E?EQUILIBRIUM lineWhat is E?
  11. 11A type of wave where the disturbance is PERPENDICULAR to the motion of the waveTRANSVERSE
  12. 12A type of wave where the disturbance is Parallel to the motion of the waveLONGITUDINAL
  13. 13What type of wave is shown?LONGITUDINALWhat type of wave is shown?
  14. 14Give an EXAMPLE of a wave that travels like the wave shownSOUNDGive an EXAMPLE of a wave that travels like the wave shown
  15. 15What type of wave is shown?TRANSVERSEWhat type of wave is shown?
  16. 16Give an EXAMPLE of a wave that travels like the wave shownWATER
    LIGHT
    X-RAYS
    GAMMA Rays
    MICROWAVES
    RADIO WAVES
    INFRARED
    ULTRAVIOLET    Give an EXAMPLE of a wave that travels like the wave shown
  17. 17The UNIT for wavelengthMETERS
  18. 18The UNIT for frequencyHERTZ
  19. 19The UNIT for wavespeedMETERS/SECOND (m/s)
  20. 20Definition of FREQUENCYHow many waves pass a given spot per second. Measured in Hertz (waves/second).
  21. 21Physical wave that requires a medium (matter) to move through.MECHANICAL
  22. 22Physical wave that DOES NOT require a medium (matter) to move through.ELECTROMAGNETIC
  23. 23A change in the direction of a wave at a boundary between two media so the wave returns to the medium from which it originatedREFLECTION
  24. 24When two waves OVERLAP to form a wave of greater, lower or same amplitude, occurs when two waves are traveling along the same mediumINTERFERENCE
  25. 25What type of INTERFERENCE is shown?CONSTRUCTIVE INTERFERENCEWhat type of INTERFERENCE is shown?
  26. 26What type of INTERFERENCE is shown?DESTRUCTIVE INTERFERENCEWhat type of INTERFERENCE is shown?
  27. 27Waves which appear to be vibrating vertically without traveling horizontally. Created from waves with identical frequency and amplitude interfering with one another while traveling in opposite directions.STANDING WAVES
  28. 28The frequency or frequencies at which an object tends to vibrate with when hit, struck, plucked, strummed or somehow disturbed is known as what?NATURAL FREQUENCY
  29. 29The happens when the frequency of a nearby object matches the natural frequency of a vibrating system and results in increased amplitude.RESONANCE
  30. 30Give 3 examples of RESONANCE we talked about in class1. Pushing someone on a swing
    2. Tacoma Narrows Bridge
    3. Breaking a glass with your voice
  31. 31What kind of wave is sound? Pick 2.Longitudinal
    Mechanical (requires medium)
  32. 32What determines the PITCH of sound?FREQUENCY
  33. 33What determines the VOLUME of sound?AMPLITUDE
  34. 34What is the DOPPLER EFFECT?An increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.What is the DOPPLER EFFECT?
  35. 35If you scream in space, will anyone hear you? Explain :)NO, Sound is a MECHANICAL wave and as such requires a MEDIUM to travel through. Space is void of matter.
  36. 36How would you change the speed that sound travels?CHANGE THE MEDIUM it travels in. Changing the wavelength, frequency or amplitude does NOT change the speed of the wave.
  37. 37What type of wave is LIGHT? Pick 2Transverse
    Electromagnetic
  38. 38List radiation type on the electromagnetic spectrum from LOWEST to HIGHEST EnergyRadio Waves
    Microwaves
    Infrared
    Visible Light
    Ultraviolet
    X-Rays
    Gamma Rays
  39. 39List the colors of visible light from LOWEST to HIGHEST energyRed
    Orange
    Yellow
    Green
    Blue
    Indigo
    Violet
  40. 40Which type of radiation has HIGHER frequency .... radio waves or ultraviolet? How do you know?Ultraviolet (HIGHER frequency waves are on the RIGHT on the EMS)
  41. 41Which type of radiation has longer wave lengths ... radio waves or visible light? How do you know?Radio Waves (LONGER wavelengths are on the LEFT on the EMS)
  42. 42What speed do all electromagnetic waves travel at?Speed of LIGHT! (3 X 10^8 m/s)
