What is Wavelength

Wavelength (nm) & the Full Spectrum

  • Wavelength determines the probability of absorption vs scattering in each type of material (tissue).
  • This is all technically "electromagnetic radiation", but the name and effect vary by wavelength (top acis), and equivalently by frequency and energy (bottom axes).
  • The blue curve represents the absorption of water throughout the spectrum.
