A geneticist looks through a microscope to determine the phenotype of a fruit fly. The microscope is set to an overall magnification of 400x with an objective lens that has a focal length of 0.40 cm. The distance between the eyepiece and objective lenses is 14 cm.
1)Find the focal length of the eyepiece lens assuming a near point of 25 cm (the closest an object can be and still be seen in focus). Do not neglect any values in your calculation.

A simple microscope consists of two lenses as shown at below. The object is just placed outside of the focal length of an objective lens with f = 5.00 mm (5.00 × 10−3 m). The focal length of the eyepiece is f=30.0mm (3.00 × 10−2 m). The microscope is being used to image a dust mite with a size of 0.30 mm. A. What is the angular size of the dust mite when observed with the naked eye at 0.30...

Q10: In a compound microscope: I know that it isnt option 4
Q12:The focal lengths of the objective lens and the eyepiece of
a microscope are 0.50 cm and 2.0 cm, respectively, and their
separation is 6.0cm when adjusted for minimum eyestrain for a
person with a near point of 25.0 cm. If the microscope is focused
on a small object, the magnitude of it final overall magnification
is closet to.

In a compound microscope, the focal length of the objective is 3.71 cm and that of the eyepiece is 6.60 cm. The distance between the lenses is 17.6 cm. (a) What is the angular magnification of the microscope if the person using it has a near point of 32.1 cm? (b) If, as normal, the first image lies just inside the focal point of the eyepiece, as in the drawing, how far is the object from the objective? (c) What...

Experiment 22: The Compound Microscope f2 Object 2 1 (Objective Lens)d L, (Eyepiece) d#150mm The Compound Microscope A compound microscope uses two lenses to provide greater magnification of near objects than is possible using a single lens as a magnifier. The setup is shown above. The objective lens, L1, functions as a projector. The object is placed just beyond the focal point of L1 so a real, magnified, inverted image is formed. The eyepiece, L2, functions as a magnifier. It...
