1 . An object 1 cm tall is 7 cm away from a lens with focal length f = 4 cm. Draw a ray diagram (full scale). Indicate clearly which is the object and which the image.

2 . For the same configuration as in part 1. Calculate the distance to the image using the lens equation.

3 . What is the percent difference between the two values you got for the distance to the image?
