Notes pb lab 05 making waves

  1. 1. Making Waves
  2. 2. Key Objectives:Key Objectives: Investigate and understand the nature anddescribe the characteristics of two typesof waves.– Transverse Waves– Longitudinal Waveshttp://www.youtube.com/watch?v=27a26e2CnuM Model, label and draw diagrams of each.
  3. 3. Key TermsKey Terms Wave Wavelength Frequency Transverse Wave Amplitude Crest Trough Longitudinal Wave Compression Rarefaction
  4. 4. Wave A disturbance thatcarries energy awayfrom its sourcethrough matter orempty space. Three categories:– Mechanical Waves– ElectromagneticWaves– Matter Waves
  5. 5. Transverse Wave A type of wave thatcan travel throughboth a medium orempty space. The energy movesperpendicular to thedirection of thewave.– Light– Water
  6. 6. Longitudinal WaveA type of wave thatmust travel througha medium.The energy movesparallel to thedirection of the wave– Sound
  7. 7. All Waves
  8. 8. WavelengthThe length of thewave.Measured from twoidentical points on awave
  9. 9. Frequency The number ofwaves counted in aspecific period oftime. (per second)– Measured in Hertz(Hz)
  10. 10. Amplitude In a transverse wave:The height or depth ordifference from therest point to the peakof a wave In a longitudinal wave:The density/thicknessof the compression
  11. 11. The Transverse Wave http://www.youtube.com/watch?v=UHcse1jJAto
  12. 12. CrestThe top point of atransverse wave
  13. 13. TroughThe lowestpoint of atransversewave
  14. 14. The Longitudinal Wavehttp://www.youtube.com/watch?v=ubRlaCCQfDk&feature=related
  15. 15. CompressionThedensest/thickpart of alongitudinalwave
  16. 16. RarefactionThe spaced outsection of alongitudinalwave betweeneachcompression
  17. 17. Essential LearningsAll waves exhibit certaincharacteristics– Wavelength refers to the length of a waveor distance between two identical pointson a wave (Length)– Frequency refers to the amount of wavesin a period of time (Speed)– Amplitude refers to the size of the energywave (Strength)
  18. 18. Essential LearningsWavelength is inverselyproportional to frequency.– Wavelength increases  Frequencydecreases– Frequency increases  Wavelengthdecreases
  19. 19. Essential LearningsTransverse Waves– Energy travels perpendicular to thewave– Do not require a medium– Amplitude is the distance from therest position to the crest or trough ofthe wave.– Light travels in Transverse Waves
  20. 20. Essential LearningsLongitudinal Waves– Energy travels parallel to the wave– The portion of this wave where it iscrowded together is called thecompression– The portion where the spacebetween compressions is greatest iscalled the rarefaction.
  21. 21. Essential LearningsLongitudinal Waves– Requires a medium– Wavelength is the distance from onecompression to the next compressionof the wave.– Sound being produced by vibrationstravels in Longitudinal Waves
  22. 22. Essential LearningsFin
