- A simple compound microscope with an overall magnification of -850 has an objective that magnifies by -250. Part (a) What is the magnification of the eyepiece? Part (b) If there is another objective that can be used, having magnification of -400, what other total magnification is possible?The power of the lenses of a certain physician’s eyes is 59 D. Assume the distance between a retina and a lens in the human eye is 2.00 cm. When she carefully examines a patient, how far, in meters, must the patient be from her?A lab technician with a near point of 27 cm is viewing a specimen with a compound microscope that has a barrel length of 16.6 cm and an eyepiece that has a focal length of 1.5 cm. Determine the focal length the objective must have so that the overall magnification of the microscope will be -291. cm
- A microscope has an eyepiece with a focal length of 18.0 mm, and an objective with a focal length of 8.00 mm. Thelenses are separated by 19.7 cm. A) If the final image is located infinitely far away, where is the object located? B) What is the total magnification?A microscope has an objective lens with a focal length of 16.22 mm and an eyepiece with a focal length of 9.06 mm. With the length of the barrel set at 33.0 cm, the diameter of a red blood cell's image subtends an angle of 1.43 mrad with the eye. If the final image distance is 33.0 cm from the eyepiece, what is the actual diameter of the red blood cell? Hint: To solve this equation, go back to basics and use the thin-lens equation. ?mAn individual is nearsighted; his near point is 11.0 cm and his far point is 51.0 cm. (a) What lens power is needed to correct his nearsightedness? 1.96 X The response you submitted has the wrong sign. diopters (b) When the lenses are in use, what is this person's near point? 11 X Your response differs from the correct answer by more than 10%. Double check your calculations. cm
