  3. ______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
  4. ______________ __________ Use the equation of the best fit line above to predict the image depth for a coral head that is 200 cm underwater.
  5. ______________ 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. What is reflection?


  7. What is refraction?
