An industrial safety officer is assessing the potential hazards associated with five different electromagnetic radiation bands used across a facility. The characteristics of these bands are:

  • Band P: Wavelength λ=4.5×10−8 m\lambda = 4.5 \times 10^{-8}\text{ m}λ=4.5×10−8 m
  • Band Q: Frequency f=5.0×1014 Hzf = 5.0 \times 10^{14}\text{ Hz}f=5.0×1014 Hz
  • Band R: Photon energy E=1.6×10−15 JE = 1.6 \times 10^{-15}\text{ J}E=1.6×10−15 J
  • Band S: Wavelength λ=1.2×10−5 m\lambda = 1.2 \times 10^{-5}\text{ m}λ=1.2×10−5 m
  • Band T: Wavelength λ=2.5×10−12 m\lambda = 2.5 \times 10^{-12}\text{ m}λ=2.5×10−12 m
