Questions about the eyepieces of telescopes: A) Which of the following are functions of the eyepiece lens of a refracting telescope? (All that apply) (a) to produce an image whose angular size is greater than that of the object (b) to magnify the image produced by the objective lens (c) to reverse the orientation of the image produced by the objective lens (d) to form an image at the focal point of the objective lens B) What must result if...
The Yerkes refracting telescope has a 1 m diameter objective lens of focal length 20 m. Assume it is used with an eyepiece of focal length 2.31 cm. Find the angular magnification of the planet Mars as seen through this telescope.
The eyepiece of a refracting telescope has a focal length of 9.00 cm. The distance between objective and eyepiece is 1.8 m, and the final image is at infinity. What is the angular magnification of the telescope?
Name 1. A refracting telescope is built with a 44.0 cm diameter objective lens that has a 1.85 m focal length It is used with an eyepiece with an angular magnification of 14.0. (a) (5 pts) What is the local length of the eyepiece? (b) (5 pts) what is the angular magnification of the telescope? (c) (5 pts) What is the distance between the objective lens and the eyeplece? 2. (5 pts) Consider a microscope with a 21.6 em tube...
Which of the following operations would increase the angular magnification of a refracting telescope? (There may be more than one correct choice.)A: Increase the focal length of the objective lens.B: Increase the focal length of the eyepiece.C: Decrease the focal length of the objective.D: Decrease the focal length of the eyepiece.E: Increase the focal length of both the objective lens and the eyepiece by the same factor.Type the letters corresponding to all the correct answers in alphabetical order. Do not...
Part A Which are the components of a typical refracting telescope? 1.convex object and eyepiece 2. concave object and convex eyepiece 3. covex object and concave eyepiece Part B Which of the following best decribes the object being viewed by the telescope? 1. object slightly outside focal length of objective 2. object slightly inside focal length of objective 3. objective essentially infinitely far away Part C The location of the object to be viewed far away results in what sort...
A refracting telescope is used to view the Moon (diameter 3480 km, distance from Earth 385,000 km). The focal lengths of the objective and eyepiece are +2.45 m and +16.1 cm, respectively. (a) What should be the distance between the lenses? m (b) What is the diameter of the image produced by the objective? cm (c) What is the angular magnification?
Galileo's Telescope Galileo's first telescope used a convex objective lens with a focal length f=1.7m and a concave eyepiece, as shown in the figure. (Figure 1)When this telescope is focused on an infinitely distant object, and produces an infinitely distant image, its angular magnification is +3.0. A. What is the focal length of the eyepiece? in cm b. How far apart are the two lenses?
3. Think about refracting telescope system of below figure for all finite distance r. Make sure that you should consider all distance regime of r explicitly. And linear magnification is calculated as Mlinear(r) = - where s is object distance, and s' is the image distance. In this two-lens system, you can first get image of object for one lens and apply that image as an object of a second lens. The sign convention for each lens applies same as...
Please answer, thank you. Part A The largest refracting telescope in the world is at Yerkes Observatory in Wisconsin. The objective lens is 1.02 m in diameter and has a focal length of 19.4 m. Suppose you want to magnify Jupiter, which is 1.38x10 km in diameter, so that its image subtends an angle of (about the same as the moon) when it is 6.28x109 km from earth. What focal length eyepiece do you need? A O O ? IVO...
