Physical Sciences/Fisiese Wetenskappe/P1/V1 10 DoE/Exemplar/Model 2008 NSC/NSS – Memorandum QUESTION 9/VRAAG 9 9.1 Diffraction/Diffraksie [12.1.2] (1) 9.2 Wavelets originating from different points in the slit reach the screen out of phase and interfere destructively on the screen. 9.3 Golffronte wat vanaf verskillende punte in die spleet ontstaan bereik die skerm uit fase en ondergaan destruktiewe interferensie. [12.2.3] (2) mλ sin θ = a ( 1)( 675 x10 = −4 1, 8 x10 = 3,75 x 10 -3 ∴ θ = 0,21° tan 0,21° = y 0, 4 −9 ) ∴y = 1,47 x 10 -3 m (1,47 mm) Width of central bright band/Breedte van sentrale helder band: 2y = 2(1,47 x 10 -3 ) = 2,93 x 10 -3 m (2,93 mm) 9.4 Increases/Toeneem Diffraction is inversely proportional to the width of the slit. Diffraksie is omgekeerd eweredig aan die breedte van die spleet. OR/OF λ Amount of diffraction is determined by the ratio . If a decreases, a λ will increase. /Hoeveelheid diffraksie word bepaal deur die a λ λ verhouding . Indien a afneem, sal toeneem. a a 9.5 Red/Rooi The yellow filter transmits red light. – yellow only transmit red and green light. When the red light reaches the magenta filter it will be transmitted – magenta only transmits red and blue light. Die geel filter laat rooi lig deur – geel laat slegs rooi en groen lig deur. Wanneer die rooi lig die magenta filter bereik, word dit deurgelaat – magenta laat slegs rooi en blou lig deur.

Physical Sciences/Fisiese Wetenskappe/P1/V1 11 DoE/Exemplar/Model 2008 NSC/NSS – Memorandum QUESTION 10/VRAAG 10 10.1 As the capacitor charges the direct current decreases and eventually becomes zero when the capacitor is fully charged. Soos wat die kapasitor laai, verminder die direkte stroom en word uiteindelik nul wanneer die kapasitor ten volle gelaai is. 10.2.1 , 2 Plate area/Plaatoppervlakte = 2 ε 0A C = d ∴200 x 10 -12 = 8,85 x 10 -12 0 , 1 d 10.2.2 0 = 0,1 m 2 [12.2.3] (2) ∴ d = 4,43 x 10 -3 m (4,43 mm) [12.1.3] (4) Plate of/Plaat van 0,1 m 2 Connecting wire/Verbindingsdraad Checklist/Kontrolelys Marks/ Criteria for diagram/Kriteria vir diagram: Punte Plates drawn parallel/Plate parallel geteken Area of plates indicated/Oppervlakte van plate aangedui Connecting wires indicated and labelled/Verbindingsdrade aangedui en benoem d = 4,43 mm Plate of/Plaat van 0,1 m 2 Distance between plates indicated/Afstand tussen plate aangedui Connecting wire/Verbindingsdraad 10.2.3 Double the distance between the plates/Increase the distance between the plates to 8,86 mm Verdubbel die afstand tussen die plate/Vermeerder die afstand tussen die plate na 8,86 mm Copyright reserved/Kopiereg voorbehou Please turn over/Blaai om asseblief [12.1.1] (4) [12.2.2] 10.3.1 Batteries store energy in chemical reactions/Batterye stoor energie in chemiese reaksies Capacitors store energy in electric fields/Kapasitors stoor energie in elektriese velde [12.2.1] (2) (1)
