They are used in various ways especially in the medical field and in security scanners at the airport.

They were discovered  by accident by a German scientist and physicist while he was working with a tube  in his laboratory.

He named them X-rays because he did not know the nature of the rays. X in  mathematics is used to designate an unknown value.
