In the diagram, draw the path of a light ray from the penny to the eye.
Plot the following data on the graph provided and draw a linear best fit line through the data points on the graph.
______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
______________ __________ Use the equation of the best fit line above to predict the image depth for a coral head that is 200 cm underwater.
______________ 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?
