papercollection2Section ABahagian A[28 marks]Answer all questions in this section.Jawab semua soalan dalam bahagian ini.1 A student carries out an experiment to study the relationship between the angle ofincidence, i, and the angle of refraction, r, when a light ray passes from air to asemicircular glass block. The apparatus set-up for this experiment is shown in Diagram1.1.Seorang murid menjalankan satu eksperimen untuk mengkaji hubungan antara suduttuju, i, dan sudut biasan, r, apabila sinar cahaya merambat dari udara ke blok kacasemibulatan.
