A hospital employs three different technologies in routine patient care:
• Magnetic Resonance Imaging (MRI)
• Diagnostic X-ray imaging
• Ultraviolet (UV-C) lamps for sterilizing surgical instruments
(a) For each technology, state the corresponding region of the electromagnetic spectrum.
(b) Rank the three regions identified in part (a) in order of increasing photon energy. Justify your ranking.
(c) For each technology, explain how the characteristic photon energy or wavelength of the radiation makes it suitable for its specific medical purpose.
