Understanding the concept of physics is very important 

Here is some concept related with physics that will help you understand many ways about them

Periode Getaran


Dengan ketentuan:

  • {\displaystyle \!T} = Periode (sekon)
  • {\displaystyle \!t} = Waktu (sekon)
  • {\displaystyle \!n} = Jumlah getaran

Frekuensi Getaran

{\displaystyle \!f={\frac {n}{t}}}

Dengan ketentuan:

  • {\displaystyle \!f} = Frekuensi (Hz)
  • {\displaystyle \!n} = Jumlah getaran
  • {\displaystyle \!t} = Waktu (sekon)

Periode Getaran

{\displaystyle \!T={\frac {1}{f}}}


Dengan ketentuan:

  • {\displaystyle \!T} = periode getaran (sekon)
  • {\displaystyle \!f} = frekuensi(Hz)

Hubungan antara Periode dan Frekuensi Getaran

Besar periode berbanding terbalik dengan frekuensi.

  • {\displaystyle \!T={\frac {1}{f}}}
  • {\displaystyle \!f={\frac {1}{T}}}

Dengan ketentuan:

  • {\displaystyle \!T} = periode (sekon)
  • {\displaystyle \!f} = frekuensi (Hz)

Gelombang

Gelombang berjalan

Persamaan gelombang:

{\displaystyle y=A\sin 2\pi (ft\pm {\frac {x}{\lambda }})}

Keterangan:

  • a: Amplitudo (m)
  • f: Frekuensi (Hz)
  • {\displaystyle \lambda }: panjang gelombang (m)

Percepatan Gelombang

Percepatan gelombag yaitu:

  1. Panjang Gelombang x Frekuensi {\displaystyle V=lamda.f}
  2. Panjang Gelombang / Periode {\displaystyle V=lamda/T}
