Question

The eyepiece of a compound microscope has a focal length of 2.90 cm , and the objective lens has f = 0.720 cm . An object is placed 0.810 cm from the objective lens. Assume a normal eye and that the final image is at infinity.

a)Calculate the distance between the lenses when the microscope is adjusted for a relaxed eye.

Express your answer to two significant figures and include the appropriate units.

b)Calculate the total magnification.

Express your answer using two significant figures.

part A is NOT .15 cm, 3.05 cm, 13.8, or 3.1 cm.

Answer #1

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 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...

A microscope has a 1.9 −cm−cm -focal-length eyepiece and a 0.80
−cm−cm objective. Assuming a relaxed normal eye.
Part A
Calculate the position of the object if the distance between the
lenses is 18.9 cmcm .
Part B
Calculate the total magnification.

A 750 × microscope uses a 0.45-cm-focal-length objective lens.

eyepiece? Assume a normal eye and that the final image is at
infinity, fe≪l.
Express your answer to two significant figures and include the
appropriate units.

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...

Your task in physics laboratory is to make a microscope from two
lenses. One lens has a focal length of 3.3 cm , the other 1.5 cm .
You plan to use the more powerful lens as the objective, and you
want the eyepiece to be 15 cm from the objective.
a. For viewing with a relaxed eye, how far should the sample be
from the objective lens?
Express your answer to two significant figures and
include the appropriate units....
