2) Light from a red HeNe laser, in the form of an S-polarized plane wave, is incident on the polished surface of a calcium uoride substrate (n = 1433) at an angle of incidence of 60 . The incident light is contained within a beam of uniform intensity, with a total power of 5mW and an area of 1mm2. Assume nair=1. a) Using the appropriate Fresnel re ection coe cient, calculate the power Pr in the re ected beam. b) Use energy conservation (Pr+Pt=Pi), calculate the power Pt in the transmitted beam. c) Using only geometry, calculate the area At of the transmitted beam, in mm2. d) Using your results from parts (b) and (c), calculate the intensity It = PtAt of the transmitted beam, in W/m2.

A simple pendulum is known to have a period of oscillation, T = 1.55 s. Student A uses a digital stopwatch to measure the total time for 5 oscillations and calculates an average period T = 1.25 s. Student B uses an analog wristwatch and the same procedure to calculate an average period for the 5 oscillations and finds T = 1.6 s. What is the most probable source of error that could explain the difference in the results? The amplitude of oscillation may have been too large for one pendulum. [5%, 10%] Human reaction time in starting and stopping the timing devices [80%, 30%] Student A mistakenly measured 4 oscillations instead of the intended 5. [5%, 20%]

A researcher wants to assess the neurotransmitter involved with cocaine usage. How might she accomplish this? She could explore the brain activity of someone who has been randomly assigned to snort cocaine compared to someone randomly assigned to a different task. She could explore the brain activity of someone who is consuming alcohol as she asks the person to also snort cocaine. She could look at the brain activity of someone who has snorted cocaine who also uses caffeine heavily. She could ask people who have snorted cocaine which of several tasks is most difficult to perform.
