X-rays of which of the following wavelengths are hardest?

X-rays region lies between

The structure of solid crystals in investigated by using

In an X-rays tube, the intensity of the emitted X-rays beam is increased by

The binding energy of the innermost electron in tungsten is 40 keV. To produce characteristic X-rays using a tungsten target in an X-rays tube the potential difference V between the cathode and the anti-cathode should be

In above question the energy of the characteristic X-rays given out is

The wavelength of most energetic X-rays emitted when a metal target is bombarded by 40 keV electrons, is approximately
(h = 6.62 × 10^–34 J-sec; 1 eV = 1.6 × 10^–19 J; c = 3 × 10⁸ m/s)

Compton effect shows that

X-rays of λ =1 Å have frequency

Mosley measured the frequency (f) of the characteristic X-rays from many metals of different atomic number (Z) and represented his results by a relation known as Mosley\'s law. This law is (a, b are constants)
