Jawab semuasoalan dalam bahagian ini.

1 A student carries out an experiment to investigate the relationship between the imagedistance, v, and the linear magnification m, of a convex lens. The apparatus is set up as

shown in Diagram 1.1

Seorang pelajar menjalankan eksperimen untuk mengkaji hubungan antara jarak

imej, v dan pembesaran linear,m untuk sebuah kanta cembung. Susunan alat radas

ditunjukkan dalam Rajah 1.1.

At the beginning, the object is placed at the distance u = 6.3 cm from the lens. The screen

is adjusted until a t sharp image is formed. The image distance, v is then measured by

using the metre rule.

The above procedure is repeated by varying the values ofu to be 6.5 cm, 6.7 cm, 6.9 cm,

and 7.1 cm.

Diagram 1.2, 1.3, 1.4, 1.5 and 1.6 on page 3, page 4 and page 5 show reading of the

metre rule when the image distance, v, is measured.

Pada permulaan, objek diletakkan pada jarak objek u = 6.3 cm daripada kanta. Skrin

dilaraskan sehingga satuimej tajam terbentuk . Jarak imej , v kemudian diukur

mengunakan pembaris meter.

Prosedur di atas diulang dengan nilai u =6.5 cm, 6.7 cm,6.9 cm, dan 7.1 cm.

Rajah 1.2, 1.3, 1.4, 1.5 dan 1.6 pada halaman 3, halaman 4 dan halaman 5
