The biggest telescopes are reflecting - instead of a main lens, they have a main mirror. Above a certain size, it is no longer feasible, or at least practical, to use lenses.

X-ray telescope mirrors are different from optical telescope mirrors. Optical telescopes use smooth, reflective surfaces to gather and focus visible light, while X-ray telescopes use nested arrays of highly polished mirror segments to reflect and focus X-rays. The design and fabrication of X-ray mirrors must be specialized to interact with X-ray wavelengths rather than visible light.
no,its obvious from ur question that:
In optical telescope mirror telescope just simple light of distant objects can be seen nearer.it is used to see distant objects.
while in x.ray telescope mirrors x.ray light can be seen.
All light telescopes have some lenses, so they use refraction at some point. The main light-gathering element in a telescope can either be a lens (refraction) or a mirror (reflection). The largest telescopes always use mirrors.
Please reach into your pocket and take out your Executive Decision Maker. (You may call it a "coin".) Please flip it, and base your decision on that.
The biggest point of difference is that reflecting telescopes can be made much larger than refractors.
No, in the sense that the two things don't have anything to do with each other. An x-ray telescope could be either a refracting telescope or a reflecting telescope.

What other application of magnetic fields uses properties similar to an MRI?
One application with properties similar to MRI is magnetic resonance spectroscopy (MRS), which also detects and analyzes the magnetic properties of atoms in the body to provide detailed information about tissue composition and metabolism.

Does the image from a radio telescope come from the same image produced by a light telescope?
Someone may need to correct me on this The image would generally look similar if the object gives off Radio waves. For example, a recent image was taken of the same Galaxy, one in Infra-red, one in visable light and one in Xray. On the Infra-Red and Visable light they look identicle, except for the colour it appears to be. Whearas the X-ray image shows only the center of the Galaxy, which tells us that the outer stars eiter give off none or a very small amount of X-ray. See the image i am referring to here http://imgsrc.hubblesite.org/hu/db/images/hs-2009-07-a-web_print.jpg

Will ultraviolet light interfer with an xray and can you combine ultraviolet light with xray?
Light will not interfere with another light. It will not combine either. Even laser beams will not interfere with one another if crossed. Only phonons in a material will react with one another.
Is the Chandra a space or land based telescope?
It is a space based XRAY telescope

What are the benefits of Optical Coherence Technology?
Optical coherence tomography is technology that allows for ultrasound resolutions of tissues. It is a lot like an xray, but it analyzes the tissues it scans. A benefit of this technology is that it is not invasive. Also it creates images in 3d which allows doctors to examine and study the images with more accuracy.
