THe current in the circuit is I. The pd across R1 is V2 and the pd acrouse R2 is V2, explain how the law of conservation of energy applies in the circuit , you should consider the movement of one coulomb of charge around the circuit. (2) - ANSWER-(1 C of) the charge gains ε J on passing through cells. - (for 2 mark) ε= IR1+IR2+Ir Prisim question path of ray info? - ANSWERSommit like the ray reflecting back outside of prism is parallel to refracting ray of light paths (I think, maybe). Geometry questions - ANSWERRemember some angle ray questions could be geometry ones. Make a prism with a larger value of θ, 2 alternatives. 1) Use a prism of the original glass in the shape of an equilateral triangle as shown in figure 9. 2) Use a prism of the original shaped made from glass with a smnalled refractive index as shown in FIgure 10. Discss wheteher either of the 2 suggests would work. (4 marks) - ANSWERUsing 60 degrees prism (fig 9) does not work because" -light would not leave the prism at the original angle. -idea that light will escape from second reflection. A smaller n (Fig 10) does not work because: -Larger critical angle. -which would reduce the value of θ.
