PPT-X rays Production of X Rays, Quality and Intensity of X Rays, Characteristics X-ray generation

X Rays Are electromagnetic radiations having wavelength of order of 1 Are highly energetic radiations which are emitted when energetic electrons are made to incident on a metallic target Were discovered by German Physicist WC Roentgen in1895.

Wavelength the size of an atom. Frequencies above UV. Uses of X-rays. 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. X-rays was discover in 1895.. X-ray are shone through the body.. Each kid of tissue lets x-rays through differently.. X-rays are very good at showing up bones.so if you break a bone it will probably be x-rayed.. point the brighter the point. The more lights you turn on the brighter the reflected light from objects in the room. See rays at right. Intensity proportional to |E|. 2. Light. source 2. Light. source 1. Accidental discovery.
