The energy in monochromatic X-rays of wavelength 1 Å is roughly equal to
What is the unit of Planck’s constant?
What are the dimensions of Planck’s constant?
An X-rays tube produces X-rays whose shortest wavelength is 0.2475 Å. The operating voltage of the tube must be
X-rays can be diffracted from crystals like the diffraction of light from a grating. The crystal grating for X-rays has a grasting element
In the continuous part of the spectrum of X-rays the limiting frequency is
An X-ray photon has a wavelength of 0.02 Å. Its momentum is
The potential difference applied to an X-ray tube is increased. As s result, in the emitted radiation,
In an X-ray tube, electrons accelerated through a very high potential difference strike a metal target. If the potential difference is increased, the speed of the emitted X-rays
An X-ray tube is operated at 66 kV. Then, in the continuous spectrum of the emitted X-rays
