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.

4(a) State the suitable inference

The brightness of the lamp increases when the speed of the magnet in the

coils(solenoid) increases// Induced current depend on the speed of

magnet

1

(b) State a relevant hypothesis

The magnitude of the induced current increases when the speed of the

magnet increases.

(c) State the aim of experiment

To study the relationship between the speed of a magnet in a coil and the

magnitude of the induced current.

1

State the suitable manipulated variables and responding variable

(Quantity that can be measured) Manipulated variables : the height of the magnet fall

Responding variables : Deflection/ reading of the galvanometer

1

State the constant variable

strenght of the magnet / number of the turns in the coils.

Draw the functional arrangement of the apparatus

1

State the method to control the manipulated variable 1. Make a solenoid of 50 turns by winding an insulated copper wire

round a cardboard tube. Connect the ends of the wire to a galvanometer.

2. Hold a small bar magnet at a height of h = 5 cm above the top end of

the solenoid.

1

State the method to measure the responding variable

3. Drop the magnet into the solenoid into the solenoid and record the

deflection of the galvanometer as the induced current.
