The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 720 nm . A) What's the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope. B) For comparison, what is this distance as a multiple of the...

A compound microscope has the objective and eyepiece mounted in a tube that is 18.8 cm long. The focal length of the eyepiece is 2.55 cm , and the near-point distance of the person using the microscope is 24.0 cm . If the person can view the image produced by the microscope with a completely relaxed eye, and the magnification is -4516, what is the distance between the objective lens and the object to be examined?

Given: Assume the near point (of the eye) is 25 cm . The distance between eyepiece and objective lens in a certain compound microscope is l = 17.6 cm . The focal length of the eyepiece is fe = 2.57 cm , and that of the objective lens is fo = 0.3 cm . What is the overall magnification of the microscope? Caution: a negative quantity this is. Use the approximation l − fe ≈ l and object distance do...
