Transcript of Interferens Gelombang

Definisi Interferens

Interferens ialah
kesan superposisi dua atau lebih gelombang
yang
koheren
Interferens Gelombang
Bab 1 Gelombang : 1 . 5
Maksud Dua Sumber
Gelombang Koheren

Dua gelombang
yang mempunyai
panjang gelombang sama
,
frekuensi sama
,
fasa gelombang sama
dan
amplitud sama.

Prinsip Superposisi

Apabila
dua gelombang
bertembung, sesaran paduan gelombang pada titik itu adalah
sama
dengan
hasil tambah sesaran
setiap komponen
Interferens Membina
Apabila puncak dua gelombang @ lembangan dua gelombang yg merambat dlm arah yg berlawanan bertemu pada satu titik, gelombang paduan dgn nilai amplitud +2a & -2a dihasilkan.
Interferens Memusnah
Pertindihan dua gelombang ini menghasilkan satu gelombang paduan dengan nilai amplitud sifar.
