Unformatted text preview: 2. Crawford 9.16 3. Use the attached page to study diﬀraction in your eye. First, look in a mirror and use a ruler to measure the width of your pupil. Then print out the attached page, which has vertical lines of various spacings. Determine the distance from your eye to the sheet at when double lines with spacing 250 μ m, 375 μ m, and 500 μ m appear to merge. Assume the wavelength of light is 550 nm, and compare the angle subtended by the merged lines with what you’d expect from diﬀraction oﬀ your pupil for these three cases. For your three distances, enter the data into the spreadsheet at: http://hep.ucsb.edu/courses/ph25/lines.xls and print out the 3 plots, and turn them in. Derive on your own, symbolically, the formulas used to make the plots in the spreadsheet. 4. Crawford 9.26  use the diﬀraction grating glasses handed out in class. 375 μ m 250 μ m 500 μ m 625 μ m 750 μ m 875 μ m...
