Question

Build a microscope that can double the size of an object. We need to choose two converging lenses from these available lenses with focal lengths 2,4,8, and 12 meters.

First choose an objective lens focal length, and a distance to place the object from the lens.

Then choose an eyepiece lens focal length and a distance to place the lens from the objective lens.

Draw your microscope design including a ray diagram.

Your diagram should include:

1. Location and properties (real/virtual, upright/inverted, bigger/smaller) of the image formed by the objective.

2. Location and properties (real/virtual, upright/inverted, bigger/smaller) of the image formed by the eyepiece.

Finally, Calculate the magnification of your microscope.

Help Thanks!

Answer #1

Determine the lens separation and object location for a
microscope made from an objective lens of focal length +1.1-cm and
an eyepiece of focal length +4.0-cm. Arrange the lenses so that a
final virtual image is formed 100 cm to the left of the eyepiece
and so that the angular magnification is -260 for a person with a
near point of 25.
B:Determine the distance between the objective lens and the
eyepiece. Express your answer with the appropriate units.
Answer...

Choose the correct statement regarding a compound
microscope being used to look at a mite.
The eyepiece lens forms a real image of the
mite.
The converging objective lens forms a virtual image of
the mite.
The eyepiece lens forms a virtual image of the
mite.
If the focal distance of the objective lens is
shortened, then its magnification decreases.
The mite should be located at the focal point of the
objective lens.

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...

Please explain, walkthrough, and show equations.

A real, upright object of 3.50 cm in height is placed to the
left of a converging lens with focal length 12.0 cm. A
diverging lens with focal length 6.00 cm is located 20.0
cm to the right of the converging lens.
Read carefully: The final image formed
by the two lens system is 5.00 cm to the right of the
converging lens.
Draw a simple yet clear diagram of the setup, labeling lenses,
object distances, and images distances as...

An
object is placed 5cm in front of a diverging lens of focal length
25 cm. A second converging lens of focal length 15cm is positioned
20 cm to the right of the first lens. What is the final image
distance? What is the magnification of the final image? Is it
upright of inverted? Real or virtual?

The focal length of the eyepiece of a certain microscope is 18.0
mm. The focal length of the objective is 9.00 mm. The distance
