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.
Explain Motion in 2 Dimensions When motion occurs in two dimensions, position, displacement and distance, speed, velocity and acceleration can be described using the x-y plane.
