1. A student carries out an experiment to investigate the relationship between the angle of incidence, i and angle of refraction, r of a glass block. The arrangement of the apparatus is shown in Diagram 1.1. A normal line is traced and the ray box is placed at the angle of incidence, i.
Seorang pelajar menjalankan satu eksperimen mengkaji hubungan antara sudut tuju , i dengan sudut biasan, r bagi suatu blok kaca. Susunan radas ditunjukkan pada Rajah 1.1. Satu garis normal disurih dan kotak sinar diletakkan pada sudut tuju, i.
Diagram 1.1
Rajah 1.1
A fine beam of light from ray box is directed to the glass block at P with angle of incidence, i 20o from the normal line. Traces of light which leaving the glass block at Q is marked with X. A line from P to Q is drawn. A protractor is used to measure the angle of refraction, r as shown in Diagram 1.2 .
Satu sinar cahaya halus ditujukan ke permukaan blok kaca di P pada sudut 20o daripada garis normal. Cahaya yang keluar pada Q ditanda dengan X. Satu garis dari P ke Q dilukis. Protraktor digunakan untuk mengukur sudut biasan, r seperti yang ditunjukkan pada
