Physics - EM Waves Question with Solution | TestHub

X – Rays radiation is a form of electromagnetic radiation. X-rays have a wavelength in the range of$0.01 \mathrm{nm}$to$10 \mathrm{nm}$, corresponding to frequencies in the range$30 \mathrm{PHz}$to$30 \mathrm{EHz}$. Therefore, they are used in studying crystals structure of solids.
