Q1. A beam of light strikes a sheet of glass at an angle of 57.0^circ with the normal in air. You observe that red light makes an angle of 38.1^circ with the normal in the glass, at the same time as violet light makes a 36.7^circ angle. What are the indexes of refraction of this glass for these colours of light?
Q2. A pair of power transmission lines each have a 0.840Ohm resistance and carry 636A over 8.92km. If the rms input voltage is 44.9kV, what will be voltage at the other end?
