Section A Bahagian A

[28 marks] / [28 markah] Answer all questions in this section.

Jawab semua soalan dalam bahagian ini. 1 A student carries out an experiment to investigate the relationship between the angle of incidence, i, and

angle of refraction, r, for light travelling from air into a glass block. The arrangement of the apparatus is shown in Diagram 1.1.

A line normal to the surface of the glass block is drawn. The position of the ray box can be adjusted so that a fine beam of light enter the glass block at different angles of incidence, i.

Seorang pelajar menjalankan satu eksperimen untuk menyiasat hubungan antara sudut tuju, i, dan

sudut biasan, r, bagi cahaya yang bergerak dari udara ke dalam satu blok kaca. Susunan radas adalah seperti ditunjukkan dalam Rajah 1.1.

Satu garis yang normal kepada permukaan blok kaca dilukis. Kedudukan kotak sinar boleh dilaras supaya satu alur cahaya yang halus memasuki blok kaca itu pada sudut-sudut tuju, i, yang berlainan.

Diagram 1.1 / Rajah 1.1 Diagram1.2 / Rajah 1.2 Initially, a fine beam of light from ray box is directed to the glass block at P with angle of incidence, i =

200. The beam of light emerging from the glass block is marked X on the white paper. The glass block is removed and a line from PX is drawn. A protractor is used to measure the angle of refraction, r, as shown in Diagram 1.2. Diagrams 1.3, 1.4, 1.5, 1.6 and 1.7 show the results obtained.

Pada awalnya, satu alur cahaya yang halus ditujukan kepada blok kaca itu di P dengan sudut tuju, i = 20o. Alur cahaya yang keluar daripada blok kaca itu ditanda X pada kertas putih. Blok kaca itu

dikeluarkan dan garis PX dilukis. Sebuah protraktor digunakan untuk mengukur sudut biasan, r, seperti ditunjukkan dalam Rajah 1.2. Rajah 1.3, 1.4, 1.5, 1.6 dan 1.7 menunjukkan keputusan yang diperoleh.
