Which one of the following parameters of the emitted X-rays increases when the potential difference between the electrodes of an X-ray tube is increased?
If V is increased, the energy of X-rays E = eV also increases. But E = hv. Hence frequency v is increased.
The wavelength of line from an element of atomic number 41 is . Then the wavelength of line of an element of atomic number 21 is
An X-rays photon of wavelength and frequency v collides with an electron and bounces off. If are respectively the wavelength and frequency of the scattered photon, then
The binding energy of the innermost electron in tungsten is 40 keV. To produce characteristics X-rays using a tungsten target in an X-ray tube, the accelerating voltage should be greater than
X-rays of wavelength are incident normally on a crystal and the second order reflection on diffraction from the crystal observed at an angle of 45o. The lattice constant of the crystal is
The frequency of line of a source of atomic number Z is proportional to
A direct X-ray photograph of the intestines is not generally taken by the radiologists because :
X-rays which can penetrate through longer distance in substances are called.
The target in an X-rays tube should be a:
The maximum frequency of the X-rays produced in an X-ray tube
Calculate the energy of a photon, in electron-volt (eV) and in watt-hour (W h), of wavelength 6600 Å.
