Wave Physics1

• Wave


  Sebuah gangguan/getaran yang merambat melalui udara dan biasanya mentransfer energi.
• Waves can take different forms, such as transverse waves (e.g. on a rope) or longitudinal/compression waves (e.g. sound waves in air)
• A single disturbance is called a wave pulse, while a series of repeated disturbances is called a periodic wave
• Mathematically, transverse and longitudinal waves can be represented similarly as a quantity (e.g. displacement, density) varying over time and space
• Gelombang transversal memiliki puncak dan lembah yang bergerak ke atas dan ke bawah, sedangkan gelombang longitudinal memiliki rapatan dan regangan yang bergerak maju mundur.
• Transverse wave:

  Osilasi dimana partikel bergerak terhadap arah gelombang. Ct:Tali dan Slinky
• Longitudinal wave

  Osilasi dimana partikel bergerak sejajar dengan arah gelombang.
• Gelombang berdiri

  Gelombang yang tercipta dari gelombang gelombang dengan frekuensi dan amplitudo yang sama dan saling mengganggu ketika merambat dalam arah yang berlawanan
• Node

  Positions on a standing wave where the wave stays in a fixed position over time because of destructive interference.
• Antinode

  Positions on a standing wave where the wave vibrates with maximum amplitude.
• Fundamental frequency

  Lowest frequency of a standing wave that has the fewest number of nodes and antinodes.
• Harmonic

  A standing wave that is a positive integer multiple of the fundamental frequency.
• Fundamental frequency

  Lowest frequency that will produce a standing wave, with one "bump" along the string length and two nodes and one antinode
• Fundamental frequency

  Wavelength is double the length of the string
• The length of the standing wave depends on the length of the string
• The endpoints will always be nodes, and the first harmonic's wavelength is double the length of the string, no matter how long the string is
