The structure of solid crystals is investigated by using

If the potential difference applied across an $X$-ray tube is $V$ volts,then the approximate minimum wavelength of the emitted $X$-rays will be:

$X$-rays incident on a material:

Absorption of $X$-rays is maximum in which of the following different sheets?

Write the sources and uses of $X$-rays and gamma rays.

What $kV$ potential is to be applied on an $X$-ray tube so that the minimum wavelength of emitted $X$-rays may be $1 \text{ Å}$? $(h = 6.625 \times 10^{-34} \text{ J-s})$
