Part I: Images Formed by a Convex Lens (Real Object outside Focal Point)

1. From your graph of the 1/d_i vs. 1/d_o. Curve-fit Equation: y = -0.984x + 0.00394

a. What should the slope of your line be? According the theoretical expression for a convex lens.

b. What is your slope?

c. Compare with a percent error calculation.

2. Using the intercept of your best-fit line, determine the focal length of the lens. Compare this calculated value to the stated value of +250 mm with a percent error. Record these values in the data table below.

3. Why 1/d vs 1/d seems like a strange thing to plot. Explain why.

A) The equation for your line has a nonzero y-intercept. Beer’s law does not have an analogous term. Explain the discrepancy between your experimental best fit equation and the theoretical Beer’s law equation. B) Consider the experimental procedure. What were the most likely sources of error? Remember that experimental error is not the same thing as a calculation mistake or incorrectly following the procedure. C) In a previous experiment we used the λmax to determine the absorbances to use for...
