SUMMARY

The discussion focuses on calculating the distance from a 35mm color slide to a projector lens and determining the image dimensions on a screen. The slide dimensions are 24x36 mm, and the projector lens has a focal length of 150 mm. Using the lens formula, 1/s + 1/s' = 1/f, participants are guided to apply simple algebra to find the slide distance from the lens and the projected image size on a screen located 9.00 m away.

PREREQUISITES
  • Understanding of the lens formula: 1/s + 1/s' = 1/f
  • Basic knowledge of optics, specifically related to projectors
  • Familiarity with algebraic manipulation
  • Concept of image formation in lenses
NEXT STEPS
  • Study the application of the lens formula in different optical systems
  • Learn about the intercept theorem and its relevance in optics
  • Explore the principles of image magnification in projectors
  • Research the effects of varying focal lengths on image projection
USEFUL FOR

Students in optics, photography enthusiasts, and professionals working with projectors who need to understand image projection calculations.

the dimensions of the picture on a 35mm color slide are 24X36 mm,an image of the slide is projected on a screen 9.00 m from the projector lens.the focal length of projectorlens is 150mm.
1-- how far is the slide from the lens
2-- what are the image on the screen.

Plz some body help me...i m not getting any clue

Do you know lens formula? Do you know intercept theorem?
 
yes lens formula is
1/s + 1/s' = 1/ f
 
Just look at what you know and what you need for the 1st part... Simple algebra.
