Homework Statement
A telescope has a mirror with a focal length of +3 meters and the distance from the mirror the the eyepiece is 3.5 meter. If the eyepiece is 3.5 meter.
a. If the eye piece has a focal length of 50 cm, where would the image produced by the eyepiece be? Could the image be projected on a screen at that location?
b. this is the case for astronomical telescopes, so how do you get an image when you look in the eyepiece? {hint: If you use a digital camera with no lens, you must reposition the eyepiece with the focus knob.}

The Attempt at a Solution
this is what i got:
a. The image would be produced at the eyepieces focal length. so 0.5m from the eyepiece. Yes this image could be projected on a screen at this location.
b.With astronomical telescopes we can see a image while looking into the eyepiece because we can adjust the eyepieces focal length until it is clear to our eyes.
Thank you
