A large reflecting telescope has an objective mirror with a 10.5 m radius of curvature. What angular magnification does it produce when a 2.95 m focal length eyepiece is used? I tried 1.77 and -1.77 and it is still wrong. Please help!!
The telescope at a small observatory has objective and eyepiece focal lengths respectively of 19.8 m and 12 cm. If this telescope is used to view a 1480 m diameter lunar crater on the surface of the moon 3.77 108 m from the surface of the Earth, determine the following. (a) angular magnification of the telescope -165 Your answer is correct. (b) size of the first image -7.8e-5m Your answer is correct. (c) length of the barrel of the telescope...
Assuming that the Magnification of a telescope is - 250, and the value of the focal length of the main objective lens (or mirror) is 1,200 mm, compute the value of the focal length of the eyepiece for this telescope. (Round your answer to the nearest whole number)
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?
A concave spherical mirror has a radius of curvature of 22 cm. Locate the images for object distances as given below. In each case, state whether the image is real or virtual and upright or inverted, and find the magnification. (If an answer does not exist, enter DNE. If an answer is infinity, enter INFINITY.) (a) p=11 cm image distance image orientation -Select- magnification 7 x cm DNE (b) p- 22 cm image distance image orientation magnification 22 cm real...
4) A concave mirror with a radius of curvature of 1.3 m is illuminated by a candle located on the symmetry axis 3.3 m from the mirror. Where is the image of the candle? Answer in units of m. 5) An object is p = 32.4 cm in front of a concave mirror. Its real image height is 6 times larger than the object height. 6) A concave mirror has a focal length of 49 cm. What is the position...
A) A small candle is 35.9 cm from a concave mirror having a radius of curvature of 21.3 cm. What is the focal length of the mirror (in cm)? B) A small candle is 41.2 cm from a concave mirror having a radius of curvature of 21.9 cm. Where will the image of the candle be located (in cm)? C)A small candle is 22.7 cm from a concave mirror having a radius of curvature of 27.3 cm. If the height...
The Galilean Telescope. The following figure is a diagram of a Galilean telescope, or opera glass, with both the object and its final image at infinity. The image I serves as a virtual object for the eyepiece. The final image is virtual and erect (Figure 1) Part A Find the angular magnification M. Part B A Galilean telescope is constructed from two lenses. the 95.0-cm lens being used as the objective. What focal length should the eyepiece have...
This is a two part question. Part 1. To look closely at a small object, such as an insect or a crystal, you bring it close to your eye, making the subtended angle and the retinal image as large as possible. But your eye cannot focus sharply on objects that are closer than the near point, so the angular size of an object is greatest when it is placed at the near point (25 cm away from a “normal” eye)....
