Photons passing through transparent material

Click For Summary
SUMMARY

Photons passing through transparent materials, such as glass, do so without significant deflection due to their interaction with groups of atoms rather than individual atoms. The wavelength of visible light, approximately 500 nm, is much larger than the size of an atom, around 0.1 nm, which means photons do not collide with atoms but instead induce polarization in the material. This polarization results in the material re-radiating the photons at the same frequency, allowing light to pass through with minimal disturbance. Scattering processes may occur, but they only slightly alter the frequency of the light.

PREREQUISITES
  • Understanding of photon behavior and light properties
  • Basic knowledge of atomic structure and size
  • Familiarity with polarization concepts in optics
  • Awareness of scattering processes in transparent materials
NEXT STEPS
  • Research the principles of light polarization in materials
  • Explore the effects of scattering on light frequency
  • Study the interaction of light with different transparent materials
  • Learn about the electromagnetic spectrum and its relation to visible light
USEFUL FOR

Students of physics, optical engineers, and anyone interested in the behavior of light in transparent materials.

Transparent materials such as glass can let visible light pass through nearly undisturbed. I don't understand how photons just pass through atoms in that material. I can understand the concept of atoms not absorbing the photons in that specific wavelengths, but how can photons avoid deflection by hitting other particles? (I'm not talking about deflection of light in different media)

The wavelength of visible light is 500 nm and the size of an atom is about 0.1 nm. That means that visible light does not interact with individual atoms, but with much larger groups. So the interaction is not like a collision and deflection. The interaction is by the photon inducing a polarization in the material, and the material re-radiating at the same frequency. This does not include some scattering processes which do change the frequency slightly.

Thank you, that really helped!
