UV and X Rays are light with a very short wave length.Let me think about the radio telescope but optical telescopes do not detect UV or X ray. Optical telescopes detect light. I'm not a astronomer so I have to think about it but if I were it would come instantaneously.
Pardon me for being "anal", but you seriously need to study some basic physics so you are familiar with the basic concepts associated with the subject of astronomy. The concepts are something a high school science student should know unless he/she is a student in the U.S. school system (which is so dumbed down that they don't know basic math or science).First, it is not physically possible to detect a radio wave from a black hole 1.3 billion light years from the earth, from the surface of the earth since a cell phone operating in China would interfere with the signal. According to physicists everything is electromagnetic wave even an electron. So, is an electron light? You take a smudge mark and you build an entire galaxy from a smudge, using a computer. Are you a Glenn or Glendina. Be a man.
