An electromagnetic radiation has an energy 14.4 keV . To which region of the electromagnetic spectrum it belongs?

Options

  1. AInfrared
  2. BVisible
  3. CUltraviolet
  4. DX-ray

Correct answer

D. X-ray

Step-by-step solution

Given radiation has 14.4 keV energy, so it is within the energy range for X-rays which is between 100 eV to 100 keV . The wavelength of given radiation, aligned & = h c E joule = 6.64 10⁻³⁴ 3 10^8 14.4 10^3 1.6 10⁻¹⁹ volt & =0.86 Å aligned X-rays have wavelength range between 0.1 A to 1 Å .
