Wave frequency is defined as the Frekuensi gelombang ditakrifkan sebagai

• distance between two successive peaks
  jarak di antara dua puncak berturutan
• highest point of the wave
  titik tertinggi gelombang
• distance between two successive peaks
  jarak di antara dua puncak berturutan
• distance between the rest position and its peak
  jarak di antara kedudukan asal dan puncak
