X-rays was discovered by scientist Rontgen that's why they are also known as Rontgen pulses.
Rontgen discovered that when pressure inside a discharge tube kept 10-3 mm of Hg and potential dissimilarity is 25 kV then some unknown radiations (X-pulses) are emitted by anode.
Production of X-rays
There are three necessary needs for the production of X-rays
(i) A source of electron
(ii) An management to accelerate the electrons
(iii) A target of suitable metal of high atomic weight and high melting point on which these high speed electrons strike.
State Gauss' theorem in electrostatics. Using this theorem, derive the expression for the electric field intensity at any point outside a uniformly charged thin spherical shell.
