  6. 6. • E.g Waves
  7. 7. Understanding wave Waves are vibrations that propagate energy from one place to another, either through the medium or no.
  8. 8. Types of waves in the direction of vibration
  9. 9. Wave
  10. 10. Wave Longitudinal waves Density Density Renggangan Renggangan Wave length = distance traveled by the wave during an interval of one period through which the medium particle vibration wave. Period particle vibration medium through which the wave is called the wave period.
  11. 11. Wave Vibration direction perpendicular to the direction of propagation Direction of propagation Vibration direction Vibration direction aligned with the direction of propagation Direction of propagation Vibration direction Wave is the propagation of vibration Wave Transverse waves Longitudinal waves
  12. 12. Based on the type of wave propagation medium
  13. 13. understanding wave
  14. 14. Mechanical wave Mechanical wave is a wave that is necessary for propagation medium. example: waves on a string, water surface waves and sound waves
  15. 15. Electromagnetic wave Electromagnetic wave is wave propagation does not require a medium. example: light waves, radio waves, X-rays, beta and gamma
  16. 16. Based on the type of wave amplitude
  17. 17. Traveling wave • Traveling wave is the wave amplitude is fixed at a point in its path.
  18. 18. Stationary wave • Stationary wave is a wave whose amplitude is not fixed at a point in its path.
  19. 19. Properties of waves
  20. 20. Properties of waves 1. waves can be reflected (reflection) 2. The waves can be refracted (refraction) 3. The wave can be bent (diffraction) 4. The wave can be combined (interference) 5. waves can be dispersed 6. waves can be polarized
  21. 21. Wave reflection • when a propagating wave and hard on the field delimiter. the angle of incidence (i) = angle of reflection (r)
  22. 22. Wave refraction • refraction that changes the direction of the wave when the wave into the new medium which resulted in a wave moving at different speeds. sin i / sin r = V1 / V2 or sin i / sin r = n1 / n2
  23. 23. Diffracted wave Bending waves caused by the presence of a barrier in the form of a gap.
  24. 24. Interferensi wave Interferensi terjadi pada dua gelombang koheren, yaitu gelombang yang memiliki frekuensi dan beda fase yang sama.
  25. 25. Wave dispersion Dispersion is spreading or decomposition of the waveform when passing through a particular medium.
  26. 26. Polarization wave Namely polarization vector vibration restriction process that forms a transverse wave so that it becomes one-way.
  27. 27. Stationary Wave Equation and Traveling Wave
  28. 28. Traveling wave equation •
  29. 29. Understand deviation traveling wave equation
  30. 30. Deviation general traveling wave equation point of origin to the top point of origin to the bottom propagating to the left propagate to the right
  31. 31. Angular frequency and wave number angular frequence wave numbers
  32. 32. Phase difference phase difference between point A and point B
  33. 33. Stationary wave equation led to remain
  34. 34. Stationary lead-free wave equation
  35. 35. Stationary wave amplitude and position of the stomach / node, the rope lead-free
  36. 36. Mendle law
  37. 37. Melde law Law seconds Report learn about quantities that affect the rapid propagation of transverse waves on a string. Through experiments seconds Report found that the wave propagation speed is proportional to the root of the wire rope tension force and inversely proportional to the mass of roots of unity length strings.
  38. 38. Wave propagation speed = distance of waves per unit of time (second). S = distance (meters) T = period (seconds) t = time (seconds) f = frequency (hertz) v = fast propagation (Meters / second) Frequency is the number of waves that pass a point every second T v λ = t S v = fxv λ=
