An X-ray Tube Is Operated At 66 KV. Then, In The Continuous Spectrum Of The Emitted X-rays

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  

The operating voltage in an X-ray tube is 10 kV. The maximum energy of the emitted X-ray photons will be 

The minimum wavelength of X-rays produced in an X-ray tube is  when the operating voltage is V. What is minimum wavelength of the X-rays when the operating voltage is ?
