Production or origin of Continuous X rays

Last time, we have discussed about the origin of name of x rays that is why x rays are known as x rays.

Today, we will discuss how x rays are produced? It is proved that whenever fast moving electrons strike a target material of high atomic number and high melting point x rays are produced. But what happen after the collision of electrons? Why and how x rays are produced then? Let us discuss it:
