A student carries outan experiment to investigate the relationship between the wavelength, Xand distance twoconsecutive brightfringe, x formonochromatic light.The studenl usedoubleslit experiment. Firstly the student located an orange filter in front ofsingle slii where iiswavelength, Xis 0.000590 mm. The distance between double slit and screen is arranged untilthe interference pattern observed. The experiment was repeated 4 times with yellow filter (X= 0.000570 mm), green filter (X = 0.000510 mm), cyanfilter (X = 0.000475 mm) and violetfilter (X = 0.000400mm). The result is shown on the graph x against X.Seorang pelajar menjalankan eksperimen untuk menyiasat hubungan antara panjanggelombang, Xdan jarak dalam pinggir cerah berturutan, x bagi cahaya-cahayamonokromatik. Pelajar itu menggunakan eksperimen dwi celah dengan meletakkan penurasjingga dihadapan celah tunggal dimana panjang gelombangnya ialah 0.000590 mm . Jarakdwi celah dengan skrin dilaraskan sehingga corak inteferen kelihatan. Jarak pinggir cerahdiukur. Eksperimen diulang 4 kali dengan menggunakan penuras kuning (X = 0.000570mm), hjau (X = 0.000510 mm), biru(X = 0.000475 mm) dan ungu (X = 0.000400 mm).Keputusan eksperimen ditunjukkan dalam grafx lawan X.

An sw e rSemiconductor is a material with electrical conductivity better thaninsulator but weaker than a conductor- Doping process/Silicon is doped with pentavalentatoms/Phosphorus/Antimony- To produce covalent bond- Increase the free electron inside the semiconductor- Majority charge-carriers is negative electron

- LDR is connected at base circuit-When intensity of light is low/ dark, resistance ofLDRincreases / so Vbasc is large / transistor switchedon- Terminal positive of batteries is connected to collector- So that the transistor is forward biased- Bulbs are arranged in parallel circuit- All bulbs are connected to voltage supply of 95V- Relay switch is used- So that the secondary circuitwill switch on // So that theelectromagnet will switchon the secondary circuit- Choose A- Because LDR is connected at base circuit, terminal positive ofbatteries is connected to collector; bulbs are arranged in parallelcircuit and relay switch is used.20 marks.
