Physical Science 20 - May 18

Today in class we finished up our notes on optics by looking at common eye problems and how they are fixed.  We learned what causes myopia and hyperopia and how to correct them  We watched a video on laser eye surgery and then talked about corrective lens power.  Notes were taken from slides 87-93.  We then had a chance to work on Homework P7.  We will take this up on Tuesday after the break.  Have a great long weekend everyone!
