- 7) Both lenses of a compound microscope have focal lengths of 1 cm. The barrel length is 26.95 cm. Deteimine the total magnification for an object placed 1.04 cn below the objective,Is this question set up wrong? I think the statement "The magnification of a book held 7.50 cm from a 10.0 cm-focal length lens is 3.00." is impossible using the lens equation 1/do + 1/di = 1/f and the equation for magnification m = -di / do.An inquiring student makes a refracting telescope by placing an objective lens and an eyepiece at opposite ends of a 46.5 cm long tube. If the eyepiece has a focal length of 1.70 cm, calculate the required focal length in cm of the objective lens and the angular magnification of the telescope. HINT (a) the required focal length in cm of the objective lens cm (b) the angular magnification of the telescope
- If the eyepiece of a telescope is replaced with an eyepiece with a focal length twice as long, the magnifying power is a. four times greater. b. two times greater. c. four times less. d. two times less.93) A simple refracting telescope provides large magnification by employing A) a short focal length objective and a short focal length eyepiece. B) a short focal length objective and a long focal length eyepiece. C) a long focal length objective and a short focal length eyepiece. D) a long focal length objective and a long focal length eyepiece. 94) A farsighted boy has a near point at 2.3 m and requires contact lenses to correct his vision to the normal near point. What is the correct choice of lens power for the contact lenses? A) -0.28 diopters B) +0.28 diopters C) -3.6 diopters D) +3.6 diopters E) +1.8 dioptersIf the eyepiece of a telescope is replaced with an eyepiece with a focal length half as long, the magnifying power is a. four times greater. b. two times greater. c. four times less. d. two times less. e. the same as with the original eyepiece.
