SAVE ME! HW DUE AT MIDNITE! Optics/Glasses problems

  1. Feb 12, 2010 #1
    1. Yang can focus on objects 170 cm away with a relaxed eye. With full accommodation, she can focus on objects 19 cm away. After her eyesight is corrected for distance vision, what will her near point be while wearing her glasses?

    2. Relevant equations
    1/o + 1/i = 1/f

    3. The attempt at a solution
    Totally Stuck!

    Not good enough. As you know from reading the rules link at the top of the page, you need to show us your attempt at a solution. Write those equations for the first scenario given (and show that to us). Write an equation for the second scenario, even if you don't know some of the values of the variables...
