   Using a convex lens, can an image be formed at the focal point and if so where would the object have to be from the convex lens?

   An object at infinity on one side of the lens will focus at the focal point on the other side.
   
   In practice, if the object is far but not at infinity, the image will still be very close to the focal point. You can calculate this using the lens equation: 1/f = 1/o + 1/i
   where
   f = focal length
   o = object distance
   i = image distance
