I am assuming that you are referencing X-rays as the actual X-Ray Machine, in which case the Radio. There have been X-Ray like devices but more like using light and a reflector, and radios can be simple metal coils that act as receivers.

∙ 11y agoTELEGRAPH came first In 1832 invented by Samuel Morse while RADIO It first became a possibility when the English physicist Michael Faraday demonstrated in 1831 that an electrical current could produce a magnetic field. In 1864, James C. Maxwell, a professor of experimental physics at Cambridge, proved mathematically that electrical disturbances could be detected at considerable distances. In 1888, a German, Heinrich Hertz, demonstrated that Maxwell's prediction was true for transmissions over short distances. The Italian physicist Guglielmo Marconi then perfected a radio system that in 1901transmitted Morse Code over the Atlantic Ocean from England to Newfoundland.

What came first radio print or moving image?
Printing began in 1345 in Germany. Next in your line of query would actually be telegraph before radio. Radio in the early 1900's and finally moving image with the invention of movies in the 1920's, but before moving image there had to be the invention of film. The camera was invented in 1830, but it didn't use film and film came about in the late 1800's. So, in sequence I would put. Print, telegraph, radio, phone, camera, film, moving image.
How was early radio different from early telegraph system?
The difference is the telegraph required wires; the radio did not. But other then that, they were mostly the same.

When was the radio brought to Ireland?
first radio station was in 1926, but there were trials from the very beginning of the radio era, mainly from the Valentia/Cahirciveen telegraph station in Kerry

Did Guglielmo Marconi invent the radio?
Guglielmo Marconi developed the first long distance wireless telegraph. He also broadcast the first transatlantic radio signal in 1901.
What replaced the radio?
telegraph
Who developed the wireless telegraph and radio?
the first to patent the wireless telegraph was Marconi. his system used spark gap transmitters and coherer detectors. it was not until effective vacuum tubes were invented that voice could be sent on radio.
What came after the telegraph?
Welll.... the telegraph replaced the pony express then the telephone replaced the telegraph. and now a days texting has replaced the telephone.
