a microscope has a converging lens (the eyepiece) with a focal length of f1=1.73cm mounted on one end of a tube of adjustable length. at the other end is another converging lens (the objective) that has a focal length of f2=29.04 cm. when you place a small flea you want to examine at a distance of s1=3.36 cm from the objective . find the overall length of the microscope needed to view the sample (the flea) in focus with a...
a microscope with converging lens (eyepiece) has a focal lenght of f1= 1.42cm mounted on one end of a tube of adjustable lenght. the other end is another converging lens (the objective)that has a focal lenght of f2=14.65 cm. when you place the flea at a distance of s1=3.20cm from the objective, find the overall lenght (cm) of the microscope needed to view the sample (a flea) in focus with a relaxed eye. hint(a normal relaxed eye will expect to...
The microscope available in your biology lab has a converging lens (the eyepiece) with a focal length of 2.50 cm mounted on one end of a tube of adjustable length. At the other end is another converging lens (the objective) that has a focal length of 1.00 cm. When you place the sample to be examined at a distance of 1.30 cm from the objective, at what length will you need to adjust the tube of the microscope in order...
need help please a microscope with a converging lens the eye part has a focal lenght f2=1.42cm . at the other end is another converging lens the objective that has a focal lenght of f1=14.65cm. when you place a bug you want to examine at a distance of s1=3.20cm from the objective. what is the overall lenght of the microscope to view the bug with a relaxed a eye. hint: a normal eye will expect to find an image at...
A compound microscope has the objective and eyepiece mounted in a tube that is 18.8 cm long. The focal length of the eyepiece is 2.55 cm , and the near-point distance of the person using the microscope is 24.0 cm . If the person can view the image produced by the microscope with a completely relaxed eye, and the magnification is -4516, what is the distance between the objective lens and the object to be examined?
A compound microscope has the objective and eyepiece mounted in a tube that is 20.0 cm long. The focal length of the eyepiece is 2.72 cm , and the near-point distance of the person using the microscope is 25.0 cm. If the person can view the image produced by the microscope with a completely relaxed eye, and the magnification is -4025, what is the focal length of the objective?
Microscope - New A microscope has a 13.0 x eyepiece and a 64.0 x objective lens 22.0 cm apart. It has been adjusted for a RELAXED normal eye. Part A Calculate the total magnification. Part B Calculate the focal length for the EYEPIECE. Part C Calculate the image distance for the OBJECTIVE.
1. On one of the shelves in your physics lab is displayed an antique telescope. A sign underneath the instrument says that the telescope has a magnification of 23.0 and consists of two converging lenses, the objective and the eyepiece, fixed at either end of a tube 81.0cm long. Assuming that this telescope would allow an observer to view a lunar crater in focus with a completely relaxed eye, what is the focal length fe of the eyepiece? Note that...
A microscope has a 9.0✕ eyepiece and a 63.0✕ objective 20.0 cm apart. (a) Calculate the total magnification. ___________✕ (b) Calculate the focal length of each lens. eyepiece _________cm objective _________cm (c) Calculate where the object must be for a normal relaxed eye to see it in focus. __________cm
an object is 1.2 cm form the objective lens of a simple compound microscope that is adjusted for a relaxed normal eye. the objective and eyepiece are 18 cm apart and the eyepiece has a focal length of 4.8 cm. what is the focal length of the objective lens?
