1 A student carries out an experiment to investigate the relationship between the image

distance, 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 of u 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

menunjukkan bacan pembaris meter bila jarak imej, v, diukur.

(c) Characteristics Reasoning

Liquid Easy to flow with blood

Short half life Not long in the body //

less harmful

Gamma Ray Cannot ionised the

living cell // high

penetrating power

GM tube detector Can detect ray

effectively// portable

K is chosen Because it is in liquid

state , has short half

life, emits gamma ray

and can be detected

easily detected by GMtube detector.
