Question

A compound microscope operated in near point adjustment comprises an objective lens of focal length 2.5 cm and an eyepiece lens of focal length 15.0 cm that are placed 20.0 cm apart. If the near-point distance is 25.0 cm, what is the overall magnification of the microscope?

Answer #1

Please let me know in the comments if the solution is correct. I
am a bit apprehensive. **Thanks**.

The focal length of the objective lens in a microscope is 0.270
cm, and an object is placed 0.275 cm from the objective.
a. How far from the objective lens will the objective image be
formed?
b. If the image of this object is viewed with the eyepiece
adjusted for minimum eyestrain (image at the far point of the eye)
for a person with normal vision. What is the needed focal length of
the eyepiece lens if the distance between...

1. The focal lengths of the objective and the eyepiece of a
microscope are 0.50 cm and 2.0 cm, respectively, and their
separation adjusted for minimum eyestrain (with the final image at
the viewer's far point) is 6.0 cm. The near point of the person
using the microscope is 25 cm and the far point is infinity.
a. If the microscope is focused on a small object, what is the
distance between the object and the objective lens?
b. If...

The tube length in compound microscope is 26 cm. The focal
length of the objective lens is 2 cm. The clearest image is formed
when an object of height 1 mm is placed at a distance of 2.18 cm
from the objective lens. Determine: 1. The position of the
intermediate image, 2. the focal length of the eye piece, that will
place the final image at the near-point, 3. the total magnification
of the microscope and the height of the...

Please explain, walkthrough, and show equations.

The medium-power objective lens in a laboratory microscope has a
focal length fobjective = 3.75 mm. If this lens produces a lateral
magnification of -53.0, what is its "working distance"; that is,
what is the distance from the object to the objective lens? What is
the focal length of an eyepiece lens that will provide an overall
magnification of -130? Assume student's near-point distance is
N=25cm.

(Part A) The medium-power objective lens in a laboratory
microscope has a focal length fobjective = 4.00 mm . If this lens
produces a lateral magnification of -37.0, what is its "working
distance"; that is, what is the distance from the object to the
objective lens? (answer in mm)
(Part B) What is the focal length of an eyepiece lens that will
provide an overall magnification of -130? Assume student's
near-point distance is N = 25 cm. (answer in cm)...

The focal eyepiece length of a compound microscope’s objective
lens is 0.400 cm and the focal length of the is 3.20 cm. The image
formed by the objective lens is 20.0 cm from the objective
lens.
a) Where is the object under study located? (1.5 pts)
b) If the image formed by the objective lens is located 3.00 cm
from the eyepiece, what is the distance l between the two
lenses? (1 pt)
c) Where is the final image located?...

The two lenses of a compound microscope are separated by a
distance of 19.0 cm. If the objective lens produces a lateral
magnification of 12.5✕ and the overall magnification is 110✕,
determine the angular magnification of the eyepiece, the focal
length of the eyepiece in cm, and the focal length of the objective
lens in cm.
(a) the angular magnification of the eyepiece
(b) the focal length of the eyepiece in cm. ____cm
(c) the focal length of the objective...

I ONLY NEED PART B!
A. A compound microscope has an objective lens
with a focal length of 15 mm and an eyepiece with a focal length of
18 mm. A specimen is placed 1.6 cm away from the objective. At what
distance from the objective does the eyepiece need to be so that an
image appears approximately at an infinite distance away from the
viewer? ANSWER: 25.8 cm
B. What is the total
magnification of the image in the...

The focal length of the eyepiece of a certain microscope is 20.0
mm. The focal length of the objective is 5.00 mm. The distance
between the objective and eyepiece is 19.7 cm. The final image
formed by the eyepiece is at infinity. Treat all lenses as
thin.
(a) What is the distance from the objective to the object being
viewed?
________cm
(b) What is the magnitude of the linear magnification produced by
the objective?
_________?
(c) What is the overall...
