frequency

Częstotliwość określa liczbę cykli zjawiska okresowego występujących w jednostce czasu. W układzie SI jednostką częstotliwości jest herc (Hz). Częstotliwość 1 herca odpowiada występowaniu jednego zdarzenia (cyklu) w ciągu 1 sekundy. Najczęściej rozważa się częstotliwość drgań, częstotliwość napięcia, częstotliwość fali.

Честотата е физична величина, мярка за измерване брой повторения на едно събитие за единица време. За да се изчисли честотата, може да се фиксира времеви интервал, да се преброят възникналите събития в интервала и след това броят да се раздели на дължината на интервала.

Frekvens er et mål for hvor hurtigt regelmæssige gentagelser af et givet  fænomen forekommer. Begrebet bruges ofte til at beskrive hvor hurtigt f.eks. bølge- eller svingnings-fænomener forløber, men mere generelt også om f.eks. bog- og bladudgivelser.Den fysiske dimension for frekvens er (tid)-1, og da SI-enheden for tid er sekund (s), bliver den tilsvarende SI-enhed for frekvens (sekund)-1 (s-1). Denne enhed kaldes også  hertz (opkaldt efter tyskeren Heinrich Rudolf Hertz, og forkortes Hz.Angives en frekvens f.eks. til 35 Hz, skal det således tolkes sådan at det beskrevne fænomen gentager sig selv regelmæssigt 35 gange hvert sekund.

A Frequency 2000-es amerikai sci-fi, dráma és thriller.A Frequency egy igen változatos mufajú film, alapvetoen "idoutazásos", tehát sci-fi keretbe ágyazza a történetet, ezenkívül thriller is, mivel egy sorozatgyilkos leleplezése lesz a cél, idon és tereken keresztül, emellett pedig érzelmekkel teli családi film is, amiben egy apa és egy fiú közel kerül egymáshoz 30 év távolságából.

A frekvencia szó szerint egy „ismétlodés gyakoriságát” jelenti, azaz hogy egy esemény hányszor ismétlodik meg egységnyi ido alatt.
