SUMMARY

Fluorescent lighting, commonly found in energy-saving light bulbs, is not polarized. The light emitted results from stimulated emission from phosphor coatings inside the tube, where ultraviolet photons generated by the excitation of mercury vapor interact with phosphor atoms. This process creates visible light that is emitted in random directions, leading to the conclusion that fluorescent light lacks polarization.

PREREQUISITES
  • Understanding of stimulated emission and photon behavior
  • Knowledge of phosphor materials and their role in light emission
  • Familiarity with mercury vapor and its excitation process
  • Basic principles of light polarization
NEXT STEPS
  • Research the properties of phosphor materials used in fluorescent lighting
  • Explore the physics of stimulated emission and its applications
  • Investigate the differences between polarized and non-polarized light
  • Learn about the mechanisms of light generation in various types of lamps
USEFUL FOR

This discussion is beneficial for physicists, lighting engineers, and anyone interested in the properties of light and its applications in lighting technology.

Hi,

I've tried looking everywhere for the answer to this, and would be fantastic if anyone could help me.

Is fluorescent lighting (found in energy saving light bulbs/lamps) polarized?

Thanks

Surely you can buy a cheap polarized filter and see for yourself?
 
No ..
The light we see from a fluourescent is due to stimulated emmission from the atoms of a phospher coating on the inside of the tube. Photons in the ultra violet are generated by the electrical excitation of mercury vapor inside the tube, these photons strike the phosphers atoms, raising their energy state forcing them to emit photons in the same direction as the photon that struct them in the visible light range. As the photons created by the excitation of the mercury are random .. the resulting "white" light is random as well .. hence not polarized ...
