1a). A scientist is testing new material to make a lens and observes that light entering this new material from air at 47.0 is refracted to 28.1. What is the index of refraction for this new material? 1b) The figure to the right shows 2 mirrors with a 120angle between the mirrors. The incident angle to the first mirror is 65. What is the angle of reflection off the second mirror? 2.A transform is plugged in in North America (V=120V and f=60Hz), 2a) What is the output voltage of this transformer if there are 5 turns in the primary and 10 turns in the secondary? 2b) The output of this transformer is connected to an RCI series circuit with R = 100, C= 10uF, and L = 70mH. What is the current in this circuit
