Experiments with Röntgen rays

In 1896, Wright had been experimenting with Crookes tube

Crookes tube

A Crookes tube is an early experimental electrical discharge tube, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, that is electrons, were discovered....

 of spherical shape to generate long exposure x-ray

X-ray

X-radiation is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 120 eV to 120 keV. They are shorter in wavelength than UV rays and longer than gamma...

 photographs. He believed the cathode rays exuded in the sphere were dynamically different from those discovered by Phillipp Lenard only a year earlier. For the future, Wright intended to research aluminum's behavior under an x-ray and its effect paired with an electric current

Electric current

Electric current is a flow of electric charge through a medium.This charge is typically carried by moving electrons in a conductor such as wire...

. Wright saw the possibility of using the rays for surgical and medical fields, predicting the rise of x-ray technology.
