X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV. They are shorter in wavelength than UV rays and longer than gamma rays. In many languages, X-radiation is called Röntgen radiation, after Wilhelm Röntgen, who is usually credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation. Correct spelling of X-ray(s) in the English language includes the variants x-ray(s) and X ray(s). XRAY is used as the phonetic pronunciation for the letter x.
X-rays up to about 10 keV (10 to 0.10 nm wavelength) are classified as "soft" X-rays, and from about 10 to 120 keV (0.10 to 0.01 nm wavelength) as "hard" X-rays, due to their penetrating abilities.
Hard X-rays can penetrate some solids and liquids, and all uncompressed gases, and their most common use is to image of the inside of objects in diagnostic radiography and crystallography. As a result, the term X-ray is metonymically used to refer to a radiographic image produced using this method, in addition to the method itself. By contrast, soft X-rays hardly penetrate matter at all; the attenuation length of 600 eV (~2 nm) X-rays in water is less than 1 micrometer.

Mr. Bean is a British comedy television programme series of 14 half-hour episodes written by and starring Rowan Atkinson as the title character. Different episodes were also written by Robin Driscoll, Richard Curtis and one by Ben Elton. The pilot episode was broadcast on ITV on 1 January 1990, with the last television episode, "Goodnight Mr. Bean" broadcast on 31 October 1995. The final episode, "Hair by Mr. Bean of London", was a video exclusive released on 15 November 1995, but not broadcast in the UK until 2006.
Based on a character originally developed by Atkinson while he was studying for his master's degree at Oxford University, the series follows the exploits of Mr. Bean, described by Atkinson as "a child in a grown man's body", in solving various problems presented by everyday tasks and often causing disruption in the process. Bean rarely speaks, and the largely physical humour of the series is derived from his interactions with other people and his unusual solutions to situations. The series was influenced by physical performers such as Jacques Tati and comic actors from silent films.
