How are X-rays produced?
Advertisements
उत्तर
The mechanical energy of electrons is transformed into the electromagnetic energy of X-rays during the production process. They are created when fast electrons smash with metal plates, releasing energy that is then absorbed by the metal plate as X-Rays.
