Do you know how X-rays are made?
We come across X-rays mostly in medical field,whenever our bones get damaged X-rays are taken so that we can come to know were exactly the bone has been fractured.In general X-rays used to scan the inner part of things which are invisible to our naked eyes.
X rays are electromagnetic rays whose wave length ranges from 0.01 to 10 nanometers.
They are produced when electrons strike a metal target. The electrons are liberated from the heated
filament and accelerated by a high voltage towards the metal target. The X-rays are produced when the electrons collide with the atoms and nuclei of the metal target.
Due to their ability to penetrate certain materials, X-rays are used for a number of nondestructive evaluation and testing (NDE/NDT) applications, particularly for identifying flaws or cracks in structural components
