Measuring thickness of hair with a laser: The experimental setup is depicted above and hair width can be solved using the formula n = w sine. First, you need to figure out a way to create a stand where you will attach the hair. A cardboard or a folded paper should do the job. Then make a small hole on the stand and attach the hair with tape so that it passes by one side of the hole. The goal is to have the hair aligned vertically and illuminate it with the laser beam. You will need to point the laser to the hole, so that it illuminates the hair to produce diffraction. Then put a screen (a paper attached to a smooth wall). You want the distance to be between one and two meters, so that your measurements will be clear, easy to make and with low uncertainty. 1. Using the above information, ANSWER the following PRE-LAB questions: a. What would happen if the distance was 20 centimeters? And 4 meters? b. What do you think will be sources of uncertainty in this experiment? c. What would happen to the diffraction pattern on the screen if your laser had a larger/smaller wavelength? wall n-th fade out Laser )0 . slit axis L If a
