PPT-X-Rays

Wavelength the size of an atom Frequencies above UV Uses of Xrays Used in airports to examine luggage for the presence of dangerous weapons or bombs or for illegal transit of goods used to detect structural deficits or cracks in metal objects such as bridges and aircraft that are likely to be missed by the human eye. Noda and Y Kamide Supervised by Y Muraki brPage 2br Have you ever had an Xray examination at the hospital In 1896 a German physicist W C R57590ntgen astonished people with an image of bones captured through the use of Xrays He had just discovered th The Future of Cosmic Ray Research. .. 8 The Future of Cosmic Ray Research . As we have seen, a few cosmic rays can be detected with energies somewhat . greater . than 10. 20. . eV. . . These high energies must be due to particle accelerations . - .
