Q1. SPM2003/P1
The diagram shows an arrangement of apparatus for light diffraction experiment.

Part C: Essay

Q2.
Figure 6.0 shows the arrangement of the apparatus for an experiment to study a
wave phenomenon.

Figure 6.1 shows the bright and dark bands of the waves pattern formed on the white paper when plane waves passes through the narrow and wide gaps.

(a) Name the wave phenomenon shown in figure 6.2. [1 mark]

(b) (i) Explain how the dark and light bands are formed on the white paper. [4 marks]

(ii) Observe Figure 6.2(a) and (b). Compare the waves patterns and the wavelength of

the waves before and after they pass through the gaps.

Relate the size of the gaps, the waves patterns and the wavelengths to deduce a

relevant physics concept. [5 marks]
