Question
The *inverted image is*
(1) Half the size of the object
(2) 1/4th the size of the object
(3) 3x the size of the object
---
The right-sided image is
(4) twice the size of the object.
I don't understand how to calculate this without focal length being known. I DO know the formula
1/f=1/p +1/i.
I also know that for magnification, we have m=-i/p. For an image with same orientation as the object, m is +. For an image with opposite orientation (IE inverted) it's negative. Thus, for the first 3 questions m=+. For the last one, m is negative.
I need an explanation that includes rationale for why I can disregard focal length, and/or substitute in something else that allows me to calculate this.
Explanation / Answer
can you post the complete question? or else i can do answers in terms of focal length
