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 hair is placed about 2 cm from the left edge. A monochromatic light at 600 nm illuminates the setup from the top. If 1 10 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
