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.

(e) 1. The connection of the wires must be tight.
2. The circuit is switched off whenever the readings were not taken
from the meters. This is to reduce energy loss from the cell.
3. The eye is perpendicular to the scale of ammeter // Pointer’s image
is not seen on the mirror strip of ammeter.
