Eksperimen / Experiment
Interferens gelombang air / Interference of water wave

Jarak antara dua garis nod yang berturutan bergantung kepada jarak antara dua sumber koheren.
Inferens
Inference The distance between two consecutive nodal lines depends on the distance between two coherent sources.

Jarak antara dua garis nod berturutan bertambah apabila jarak antara dua sumber koheren berkurang.
The distance between two consecutive nodal lines increases as the distance between two coherent sources
Hipotesis
Hypothesis decreases.

Mengkaji hubungan antara jarak antara dua sumber koheren, a, dan jarak antara dua garis nod yang
Tujuan berturutan, x.
