Overview
1.The following is a graph of the inverse image distance (1/di) vs the inverse object distance (1/do):
Determine the slope of this graph to at least 2 significant figures.

- You have a candle, a meterstick, and a piece of page to act as image screen. You place the candle and the lens and then move the screen to obtain a sharp image. The locations of these three objects along the meterstick are 25 cm, 41 cm, and 65 cm, respectively. The flame is 1.8 cm long, and its projection on the screen appears to be 2.8 cm long. Determine the theoretical value for the image magnification to at least 2 significant figures.
3.The following is a graph of the inverse image distance (1/di) vs the inverse object distance (1/do):
Determine the percent error of the slope of this graph to at least 2 significant figures.
