5. The magnification of a telescope is the effective focal length (efl) of the telelscope optics
divided by the focal length of the eyepiece, and the results should be unitless (ie
magnification does not have things like mm or inches in it). Calculate the magnification
of the following systems. Show your work. (note eyepieces are interchangeable, so
astronomers generally don't care about the magnification - if it doesn't look good, we just
change the eyepiece.)
a. efl: 80 inches, eyepiece: 40 mm
|
b. efl: 80 inches; eyepiece 25 mm
c. efl: 325 cm; eyepiece 35 mm
