SUMMARY

The discussion centers on calculating the angular magnification of a simple magnifier using a lens with a focal length of 50 cm. The relevant equations for this calculation are m = N/d, where d is the distance of the object, and m = 1 + N/f, where N is the near point (25 cm) and f is the focal length (50 cm). The user successfully identifies the equations needed to solve the problem, confirming that they can proceed with the calculations.

PREREQUISITES
  • Understanding of lens focal length and its implications in optics
  • Knowledge of angular magnification concepts
  • Familiarity with basic optical equations
  • Ability to perform calculations involving distances in optics

Homework Statement


A lens having a focal length 50 cm is used as
a simple magnifier.

What is the angular magnification obtained
when the image is formed at the normal near
point (25 cm)?


Homework Equations



1) m = N/d, where d is distance of object

2) m = 1 + N/f

I don't really get what do they want as the answer.

Also, there are two equations, which one do I use?

THanks! :)
