Question1
One of the ways that a forensic scientist can figure out the make and model of a car from a "hit and run" collision is if they be able to pick up a piece of plastic from the headlight of the car. The plastics in a car tend to be different for different makes and models of cars and thus have different index of refractions that you can find in a table. If you were given a flat piece of plastic from a hit and run, write down a procedure to figure out what type of car was involved in the hit and run.
Question2
Two people are talking at a distance of 2.49 m from where you are and you measure the sound intensity as 1.47×10^-7 W/m2. Another student is 4.79 m away from the talkers. What sound intensity does the other student measure?
