CAN YOU tell me all you know about X-rays?THANKS!?

Question

how does it function?its putrpose?effect?harm?what is it?

Answer 1

X-rays are electromagnetic radiation, which means that they are "light." The rays have frequencies of10^16 to 10^20 Hertz and wavelengths of 10^-8 to 10^-10 meters. This means that they are higher in energy, higher in frequency, and shorter in wavelength than ultraviolet light, which in turn is higher in energy than visible light. The only electromagnetic radiation higher in energy, shorter in wavelength, and higher in frequency are gamma rays, emitted during nuclear reactions. One produces x-rays by blasting a stream of electrons at some metal surface. The electrons knock electrons out of the innermost K-shell (1s-orbital) of the metal atoms. The upper electrons in the metal atoms come cascading down, emitting x-rays of specific frequency when they fill the K-shell space again.

X-rays are ionizing radiation. That means that they'll knock electrons out of atoms in human tissue, leading to free radicals and ions. Excessive x-ray doses lead to longterm illnesses.

X-rays are used to image bones and organs in humans and animals. They are also used to destroy cancerous tumors, because they are slightly more destructive of cancer cells than normal cells (radiation therapy). They are used to identify scrap metal by the characteristic frequencies of x-rays that the metals produce (x-ray fluorescence). They can determine the structures of complicated molecules by diffraction patterns of x-rays by crystals of these molecules.

Answer 2

it takes a picture of your bones and really doesnt hurt its like a photo at christmas except w/o the bright flash

Answer 3

x-rays are harmful because they mess up your genes.
