SOLVED:A homemade compound microscope has, as objective and eyepiece, thin lenses of focal lengths 1 cm and 3 cm, respectively. An object is situated at a distance of 1.20 cm from the objective. If the virtual image produced by the eyepiece is 25 cm from the eye, compute (a) the magnifying power of the microscope and (b) the separation of the lenses.

(II) The eyepiece of a compound microscope has a focal length of 2.80 cm and the objective lens has f = 0.740 cm. If an object is placed 0.790 cm from the objective lens, calculate (a) the distance between the lenses when the microscope is adjusted for a relaxed eye, and (b) the total magnification. | Numerade

SOLVED: The eyepiece of a compound microscope has a focal length of 2.50 cm, and the objective lens has f = 0.740 cm. An object is placed 0.790 cm from the objective lens. Assume a normal eye and that the final image is at infinity. Calculate the distance between the lenses when the microscope is adjusted for a relaxed eye. Calculate the total magnification.

SOLVED:Given two 12-cm-focal-length lenses, you attempt to make a crude microscope using them.While holding these lenses a distance 55 cm apart, you position your microscope so that its objective lens is distance from a small object. Assume your eye's near point N = 25 cm. (a) For your microscope to function properly, what should d∘ be? (b) Assuming your eye is relaxed when using it, what magnification M does your microscope achieve? (c) Since the length of your microscope is not much greater th

SOLVED:The focal length of the eyepiece of a certain microscope is 18.0 mm . The focal length of the objective is 8.00 mm . The distance between objective and eyepiece is 19.7 cm . The final image formed by the eyepiece is at infinity. Treat all lenses as thin. (a) What is the distance from the objective to the object being viewed? (b) What is the magnitude of the linear magnification produced by the objective? (c) What is the overall angular magnification of the microscope?
