SUMMARY

The discussion focuses on solving a homework problem related to converging lenses, specifically using the lens formula 1/v + 1/u = 1/f. The participant rules out options B and D based on the conditions for producing enlarged real and virtual images. They emphasize the importance of determining whether the image is real or virtual before applying the magnification equation to find the correct answer. The context indicates that the lens is functioning as a magnifying glass, which requires the object to be placed within the focal length of the lens.

PREREQUISITES
  • Understanding of the lens formula (1/v + 1/u = 1/f)
  • Knowledge of real and virtual images in optics
  • Familiarity with magnification equations
  • Experience with optical applets for visualizing lens behavior
NEXT STEPS
  • Study the properties of converging lenses and their applications
  • Learn how to derive and apply the magnification equation in different scenarios
  • Explore the use of optical applets for simulating lens behavior
  • Investigate the differences between real and virtual images in various optical systems
USEFUL FOR

Students studying optics, physics educators, and anyone seeking to understand the principles of converging lenses and image formation.

I'm not sure any, perhaps 1/v + 1/u = 1/f

The Attempt at a Solution


[/B]
I knowp enlargened real images will only be produced if the object distance is lower than the image distance, so that rules out B. Similarly I know that enlargened virtual images can only be produced if the object distance is less than the image distance, so that rules out D.

I'm not sure how to figure whether it's A or C, playing around in applets I can produce an image twice as big under both conditions.

Forget the applets. First decide whether the image is real or virtual. Then use the magnification equation to figure out the answer.
 
The lens is used as a magnifying glass.
This means that the object is placed where with respect to the lens?
