  2. Draw a linear best fit line through the data points on the graph.
  3. ______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
  4. ______________ The above material is reported to have a theoretic index of refraction of 1.33. What is the percentage error for the slope you calculated based against a theoretic value of 1.33?

  6. __________ By what percentage does an object underwater appear to a SCUBA diver?
  7. What is an image?
  8. _________________ Is the image inside a pinhole camera right-side-up or upside-down?
  9. _________________ Is the image produced by a convex lens right-side-up or upside-down?
  10. What is myopia?
  11. What is presbyopia?
  12. What is the typical treatment for presbyopia?

[ slope m= (y2−y1) (x2−x1) ] [ Δ% = (observed−predicted) predicted ]
