Angular Magnification of a telescope,

Click For Summary
SUMMARY

The discussion centers on calculating the angular magnification of a telescope with a mirror radius of curvature of 14.0 m and an eyepiece focal length of 19.0 cm. The participant seeks assistance due to a lack of access to the necessary equations in their cyber-school program. The key formula for magnification, m = height of image/height of object, is mentioned but deemed insufficient for solving the problem. The conversation emphasizes the importance of providing more context and effort when seeking help in academic forums.

PREREQUISITES
  • Understanding of basic optics principles, specifically magnification.
  • Familiarity with telescope components, including mirrors and eyepieces.
  • Knowledge of the formula for angular magnification.
  • Basic problem-solving skills in physics.
NEXT STEPS
  • Research the formula for angular magnification in telescopes.
  • Learn about the differences between Galilean and Newtonian telescopes.
  • Study the relationship between focal length and radius of curvature in optics.
  • Explore common optical equations used in telescope design.
USEFUL FOR

Students in physics, particularly those studying optics and telescope mechanics, as well as educators looking for insights on teaching magnification concepts.

Homework Statement


A telescope consists of a mirror with radius of curvature 14.0 m and an eyepiece of focal length 19.0 cm. Approximately what is the value of its angular magnification

I haven't yet been asked to find angular magnification given such little detail, my cyber-school program doesn't give me the necessary equation for this particular problem and my teacher is on vacation so if someone could give me a tiny hint I'd be tickled pink.


Homework Equations


m=height of image/height of object (my cyberschool says it's useful but I disagree)


The Attempt at a Solution


no clue

Hello Bleiter, and welcome to PF.

Looks like you are ill-equipped to deal with the exercise at hand! Just quoting the definition of magnification factor doesn't suffice under 2. and "no clue" under 3. doesn't count at all. In fact, the folks at PF don't just dislike that, they even put it in the rules, which please get acquainted with.

It's not just for you, also for potential helping hands: I for instance have no idea what a cyberclass is and whether that is before a PhD or beyond.

So show a little more, google around and tell us where precisely you get stuck. Would the same exercise but with a Galilean telescope be a piece of cake for you, or would it leave you equally clueless?
