SUMMARY

The discussion centers on calculating the image distance produced by a lens placed at the origin, which creates a real inverted image at x = -24 cm. The magnification formula m = -d'/d was applied, leading to the conclusion that the image distance d' is 48 cm. The user initially miscalculated the object distance but later corrected their approach, confirming the image distance as 48 cm based on the magnification of -2.

PREREQUISITES
  • Understanding of lens formulas, specifically the magnification equation m = -d'/d
  • Familiarity with the concepts of real and inverted images in optics
  • Basic knowledge of object and image distances in lens systems
  • Ability to manipulate algebraic equations to solve for unknowns
NEXT STEPS
  • Study the lens formula: 1/f = 1/d + 1/d' for more comprehensive lens analysis
  • Explore the concept of magnification in different lens types, including concave and convex lenses
  • Learn about ray diagrams to visualize image formation by lenses
  • Investigate the impact of lens curvature on image distance and quality
USEFUL FOR

Students studying optics, physics educators, and anyone involved in understanding lens behavior and image formation principles.

Homework Statement



A lens placed at the origin with its axis pointing along the x-axis produces a real inverted image at x = -24 cm that is twice as tall as the object

What is the image distance?

Homework Equations



m = -d'/d

The Attempt at a Solution



I thought d=24 cm. and h' = -2h
then use m = h'/h to solve for the m. which I got m = -2.
then I used m = -d'/d
-2 = -d'/24
d' = 48 cm.

I don't know where I did wrong..
please help me..
thanks..
