X-rays Are Incident Normally On A Crystal Of Lattice Constant 0.6 Nm. The First Order Reflection On Diffraction From The Crystal Occurs At An Angle Of 30o. What Is The Wavelength Of X-rays Used? 

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 

An X-ray tube is operated at 66 kV. Then, in the continuous spectrum of the emitted X-rays

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 ?   

The maximum frequency of X-rays produced in an X-ray tube is v when the operating voltage is V. What is the maximum frequency of the X-rays when the operating voltage is ?   

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
