1. continuous x-rays Due to the electron, x-ray tube in to smash atoms of the metal target, losing energy. The power will be put up in electromagnetic waves with a wavelength depends on the kinetic energy of the electron.
1. x-rays constantly The origins of the X-ray tube electrons in the atoms of the metal raced to the target and then losing power. It will emit energy in the form of electromagnetic waves with different wavelengths depending on the energy of the electrons.
1.The X-ray continuum. Due to the electrons in the X-ray tube ran into atoms of metal targets and lose energy. The emit energy that come out in the form of electromagnetic radiation with wavelengths conditions.
