Part A: What is the magnification of an astronomical telescope whose objective lens has a focal length of 71cm and whose eyepiece has a focal length of 2.9cm? Follow the sign conventions. Part B: What is the overall length of the telescope when adjusted for a relaxed eye?
Part A What is the magnification of an astronomical telescope whose objective lens has a focal length of 73 cm and whose eyepiece has a focal length of 2.6 cm ? Follow the sign conventions. Part B What is the overall length of the telescope when adjusted for a relaxed eye?
Two lens with different focal length are made as a telescope. If the magnification is 16 and the length of telescope is 85 cm, how much is the focal length of eye lens?
What is the magnification of a telescope which has an objective lens of focal length 2.50 m and a diameter of 1.00 m, and an eyepiece of focal length 4.50 cm? What is the angular resolution of this telescope for visible light (wavelength = 550 nm)? What is the length of the telescope?
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.
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?
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...
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...
An astronomical telescope has its two lenses spaced 82.9 cm apart. If the objective lens has a focal length of 78.5 cm , what is the magnification of this telescope? Assume a relaxed eye. Follow the sign conventions.
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?
