A student carries out an experiment to investigate the relationship between the sine of the angle of incidence, i and the sine of the angle of refraction, r of a glass
block.

Refracted ray
FIGURE 1.1 /RAJAH 1.1
A ray of light is directed along the angle of incidence, i = 20o and forms the angle
of refraction, r. The angle of refraction is measured by using a protractor. The
corresponding reading of r1 , is shown in Figure 1.2 on page 5.
The experiment is repeated by varying the angle of incidence, i, to 30o, 40o, 50o
and 60o. The corresponding angles of refraction, r are shown in Figures 1.3, 1.4,
1.5 and 1.6 on pages 6 and 7 respectively.

Paper 3 Part B
Diagram 3.1 shows a worker pushing down on the piston of a clogged bicycle pump. Diagram 3.2 shows
the same worker finding it harder to push the piston further down.
With the use of apparatus such as a Bourdon gauge and other apparatus, describe an experiment to
investigate the hypothesis stated.
4. Diagram 4.1 show a lamp which lights up with normal brightness when the dimmer knob is set at its
minimum value. Diagram 4.2 shows the lamp dimmer when the dimmer knob is set at its maximum
value.
With the use of apparatus such as constantan wire, voltmeter and other apparatus, describe an
experiment to investigate the hypothesis stated.
