Solution

Solution

The correct option is B)Roentgen

Explanation

German physics professor Wilhelm Roentgen was the first person to identify electromagnetic radiation with a wavelength range currently known as X-rays. Although many people had previously seen the effects of X-ray beams, Roentgen was the first to thoroughly investigate them. Although they are now referred to as Roentgen rays, he called them X-rays to emphasise the novel character of his discovery. For his outstanding accomplishment, he received the first Nobel Prize in Physics in 1901.

  • We can define X-Rays or X-radiation as form of electromagnetic radiation.
  • They are powerful waves of electromagnetic energy.
  • Most of them have a wavelength ranging from 0.01 to 10 nanometres, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 100 eV to 100 keV.
