garis normal berada pada Ciri-ciri Pantulan
satah yang sama Gelombang
Incident wave, reflected Characteristics of
wave and the normal lie in Reflection of Wave Frekuensi tetap
the same plane Constant frequency
(f)

Arah perambatan Halaju tetap

Direction of wave (v)
propagation changed

Eksperimen / Experiment Pantulan gelombang / Reflection of wave

Inferens Sudut pantulan bergantung pada sudut tuju.
Inference The angle of reflection depends on the angle of incidence.

Hipotesis Sudut pantulan bertambah apabila sudut tuju bertambah.
Hypothesis The angle of reflection increases as the angle of incidence increases.

Tujuan Untuk mengkaji hubungan antara sudut tuju dan sudut pantulan.
eksperimen
Aim of the To investigate the relationship between the angle of incidence and the angle of reflection.
