X Rays

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

Determine the type of x-ray emitted as shown in the figure.

• continuous x ray.

• characteristic x ray.

Line spectrum of hydrogen atom does not include the X-ray frequencies because ...

• hydrogen atom does not contain neutrons.

• hydrogen cannot be elevated to a sufficiently high temperature.

• there is too few energy levels in hydrogen atom.

• the ionization energy of hydrogen atom is low.
