A microscope has an objective lens of focal length 00 mm. The objective forms an image 18 cm from the lens. The focal length of the eyepiece is 70 cm. What is the distance between the lenses?
A microscope has an objective lens with a focal length of 15.0 mm . A small object is placed 0.90 mm beyond the focal point of the objective lens. Part A) At what distance from the objective lens does a real image of the object form? My answer: s' = 270 mm Part B) What is the magnification of the real image? My answer: m = -17 Part C) If an eyepiece with a focal length of 2.5 cm is...
The barrel of a compound microscope is 16.2 cm in length. The specimen will be mounted 1.11 cm from the objective, and the eyepiece has a 5.20 cm focal length. Determine the focal length of the objective lens.
A microscope has an objective lens with a focal length of 10.0 mm . A small object is placed 0.90 mm beyond the focal point of the objective lens. If an eyepiece with a focal length of 2.5 cm is used, with a final image at infinity, what will be the overall angular magnification of the object? Express your answer using two significant figures.
A compound microscope has an objective lens with a focal length of 0.40 cm and an ocular (eyepiece) with a focal length of 4.25 cm. The separation between the lenses is 20 cm. (a) Find the total magnification. (b) What focal length of the objective should be used to double the total magnification, if the focal length of the eyepiece and its separation from the objective remain the same?
A microscope has an objective with a 4 mm focal length and an ocular with a 30 mm focal length. The two lenses are separated by 0.16 m, and the final image is formed 0.25 m from the ocular. a. Where is the image formed by the objective? b. Where is the specimen relative to the objective? c. What is the magnification of the microscope? d. Neglecting any diffraction effects, what is the smallest separation between two points that can...
A microscope consists of a convergent objective with focal length 15 mm and a convergent eyepiece with a focal length of 60 mm separated by a fixed distance of 80 cm. What is the total magnification achieved when observing an ant at a distance of 44 mm from the objective? Lens 1 Lens 2 2.5 cm 4 cm 10 cm
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...
