X-Rays
Category : JEE Main & Advanced
(1) X-rays were discovered by scientist Rontgen thats why they are also called Rontgen rays.
(2) Rontgen discovered that when pressure inside a discharge tube is kept \[{{10}^{-3}}\,mm\] of Hg and potential difference is kept 25 kV, then some unknown radiations (X-rays) are emitted by anode.
(3) There are three essential requirements for the production of X-rays.
(i) A source of electron
(ii) An arrangement to accelerate the electrons
(iii) A target of suitable material of high atomic weight and high melting point on which these high speed electrons strike.
