Which of these is NOT true about the x-ray tube for production of x-ray?
a vacuumed glass tube is used to prevent electron from hitting the air molecules.
the cathode consists of heated filament with high ionization energy.
cooling system is required at the anode metal target in order to prevent the metal from melting
the metal target of anode should be metal with high melting point.
Rearrange these statements to describe the production of x-ray:
I. The high speed electrons rapidly decelerated on the impact, and x-rays are emitted.
II. The high voltage current supply heat the filament cathode (to emit electrons at high acceleration).
III. Electrons emitted are accelerated towards a metal target.
I, II, III
II, III, I
II, III, I
II, I, III
