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.
what is virtual displacement?and how is it different from actual displacement?
It is defined as an electric strain produced in an atom due to application of external electric field to the bulk material. It is the result of the displacement of the positively c
APPLICATIONS OF NEWTON'S LAWS - I 1. The conclusion from F = ma is that if F = 0 then a = 0 ! quite easy! yet how powerful ! This says that for anybody which is no
