Concept explainers
The maximum magnification.
Answer to Problem 69GP
The magnification power is
Explanation of Solution
Given info:
Power of lens
Distance between the objective lens and the eyepiece of telescope is
Formula used:
The focal length is the inverse of power. So,
Where,
Where,
Calculation:
The focal length of the eyepiece is
For both object as well as image far away, the focal length of the objective from separation of the lenses is
So, focus length of object is
The magnification of the telescope is given by
Conclusion: The required value is
