The energy of the em waves is of the order of 15   keV . To which part of the spectrum does it belong?

Options

  1. AInfra-red rays
  2. BUltraviolet rays
  3. Cγ -rays
  4. DX-rays

Correct answer

D. X-rays

Step-by-step solution

Wavelength of the ray λ = h c E = 12400 15000 = 0.826   Å X-ray wavelengths are in the range 0 . 5   –   2 . 5   Å , so it is an X-ray.
