SUMMARY

The discussion centers on calculating the magnification of a telescope with a focal length of 200 cm for the objective and 1 cm for the eyepiece. The correct formula for magnification (M) is M = Fo/Fe, where Fo is the focal length of the objective and Fe is the focal length of the eyepiece. The user incorrectly calculated the magnification as 200 instead of the correct value of 20, which is derived from the formula when considering the focal lengths provided.

PREREQUISITES
  • Understanding of telescope optics and magnification principles
  • Familiarity with focal lengths and their significance in optics
  • Basic algebra for manipulating equations
  • Knowledge of how to apply formulas in physics
NEXT STEPS
  • Study the principles of optical magnification in telescopes
  • Learn about the relationship between focal lengths in optical systems
  • Explore the concept of viewing objects at infinity in optics
  • Review common mistakes in calculating magnification in telescopes
USEFUL FOR

Students studying physics, particularly those focusing on optics, as well as educators and anyone interested in understanding telescope functionality and magnification calculations.

I have been working on this problem for HOURS! PLease helpe me!

Homework Statement


The objective of a telescope has a focal length of 200 cm and its eye piece has a focal length of 1 cm. What is the magnification of this telescope when viewing an object at infinity??


Homework Equations





The Attempt at a Solution



I thought ...
M = Fo/Fe which would = 200 but the answer is 20! Why? Does infinity have something to do with it??
 
Physics news on Phys.org
Anyone know about this??
