History Of X Ray
An x ray or x radiation is a penetrating form of high energy electromagnetic radiation most x rays have a wavelength ranging from 10 picometres to 10 nanometres corresponding to frequencies in the range 30 petahertz to 30 exahertz 3 10 16 hz to 3 10 19 hz and energies in the range 124 ev to 124 kev x ray wavelengths are shorter than those of uv rays and typically longer than those of.
