why does shorter wavelengths produce a clearer image?
why is wavelength the limiting factor in magnification and clarity?

The wavelength limits the resolution (two-point-discrimination) of the picture. The minimal distance between two points cannot be smaler than the wavelength of the electromagnetic wave itself, which is reflected by the object.
So the shorter wavelength, the smaler the minimal possible distance between two points.
This means that ultrasound pictures (in medicine) will never have the resolution of an optical picture. And an optical picture will not have the resolution of an x-ray-picture.

The reflectivity of a material. If u can reflect several wave lengths it will be blurred. Especially when u get in the shorter than a half wave length. X rays work the best for very small things.
