Ans : X - ray region .
The energy of electromagnetic radiation depends upon the frequency or wavelength of incident radiation.
e.g., E = hv = hc/λ { here v is the frequency of incident radiation }
we know, formula of energy in eV when wavelength given in nm is
E = 1240/wavelength (in nm)
given, E = 13.2 KeV = 13200 eV
13200 eV = 1240/wavelength
wavelength = 1240/13200 = 0.0939 nm
now see pic , you observed this wavelength belongs to X-ray region { 1nm - 1pm }
Hence, the radiation is related to X - ray region .
