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 low voltage current supply heats the filament cathode to emit electrons.
III. Electrons emitted are accelerated through a large potential difference towards a metal target.

What are the two distinct components of X-rays spectrum?
- a continuous distribution of wavelengths with a sharp cut-off at short wavelength
- a series of high-intensity spikes
- a continuous distribution of wavelengths with a sharp cut-off at long wavelength
- a series of high-intensity spikes
- a discontinuous distribution of wavelengths with a sharp cut-off at long wavelength
- a series of high-intensity spikes
- a continuous distribution of wavelengths with a sharp cut-off at long wavelength
- a series of low-intensity spikes
Select relevant statements to explain why a continuous spectrum of wavelength is produced.
EM radiation is produced whenever a charged particle is accelerated/decelerated.
Wavelength depends on magnitude of acceleration.
Electrons have a distribution of accelerations/decelerations.
EM radiation is produced whenever a charged particles travels at a constant speed.
