A converging lens with a focal length of 19 cm is used to form an image on a screen that is 3.3 m to the right the lens. Where must the object be placed?
____m to the left of the lens?
Have you seen an equation that looks something like
1/Do + I/Df = 1/f ?
Well, you have now.
Di = image distance = 3.3 m
f = focal length = 0.19 m
Solve for Do (object distance) in meters
The object is close to the focal point. You have a highly magnified image
