Question
I need to double check my answers, before submitting.
What is the magnification equation?
Magnification = 1/f + 1/q
Magnification = -qp-1
Magnification = 1/q + 1/p<--------------------I pick this one.
Magnification = qp-1
Magnification = -pq-1
Magnification = -qp-2
What is the purpose for the eye-piece in the lens combination?
The eye-piece takes the objective's real image and creates a magnified virtual image.
The eye-piece takes the real object and creates a virtual image.
The eye-piece takes the objective's real image and creates a magnified real image.<-------My answer.
The objective takes eye-piece's real image and creates a magnified real image.
Given an object distance of 30[mm] and a thin-lens focal length of 146[mm], then what is the image distance? . Answer with three significant figures or N/A if there is not enough information.
I got ----->-37.8 [mm]
What is the scale factor (M) of the image seen in the previous question? 1.26 Answer with three significant figures or N/A if there is not enough information.
I got -------------->1.26
Explanation / Answer
The eye-piece takes the objective's real image and creates a magnified real image.
u = -3 cm
f = 14.6 cm
1/v - 1/u = 1/f
v = -3.77 cm
m = v/u = 1.258
