Problem 3 (25 points): A pair of glass slides are set up in air to measure the diameter of a cat hair (see below). The left edge of the top glass slide touches the bottom glass slide. A cat's hair is placed about 2 cm from the left edge. A monochromatic light at 600 nm illuminates the setup from the top. If 110 bright fringes are observed (when seen from above) between the top glass slide's left edge and the cat hair, what is the hair's diameter? glass slide glass slide Cat hair
