Question

how is kinetic energy used to produce x rays?? detail

answer please. thank you

Answer 1

An X-ray tube generally consists of two main components: cathode and Anode.

They are conncted outside in a circuit where an accelerating voltage is applied.

Generally the cathode is a thermionic material such as aluminum and the anode is the target made up of material such as Platinum.

cathode is connected to the negative terminal and anode is connected to the positive terminal.

As the circuit is turned on and a certain voltage is applied across the terminals, the cathode begans to heat up and as it is a thermionic material it emitts electrons. Due to an already prevalent potential difference between the cathode andd the anode, the electrons starts to accelerate and with the incraese in voltage. After a sufficient increase in voltage, the electrons gather enough kinetic energy to strike the anode target.

After collision the electron looses its velocity i.e., kinetic energy. As energy is conserved, the change in kinetic energy is usually emitted as X-ray and is also called the "Braking radiation".
