Theoretical 100% Light Reflection Room

Click For Summary
SUMMARY

A theoretical room with 100% reflective walls would not remain illuminated after the instantaneous removal of a light source, as light would dissipate almost immediately. If an object were present in the room before the light source was removed, the reflections would become unrecognizable within microseconds. The concept of using remaining photons to identify an object in a real-life scenario, such as a crime scene, is impractical due to the lack of actual 100% reflective environments and the rapid dissipation of light.

PREREQUISITES
  • Understanding of light behavior and reflection principles
  • Familiarity with the concept of photon absorption
  • Knowledge of optics and light propagation
  • Basic principles of crime scene investigation
NEXT STEPS
  • Research the physics of light reflection and absorption
  • Explore the concept of photon behavior in closed environments
  • Investigate real-world applications of light in forensic science
  • Learn about advanced optical materials and their properties
USEFUL FOR

Physicists, optical engineers, forensic scientists, and anyone interested in the theoretical implications of light behavior in reflective environments.

If there was a room with all walls that are 100% reflective and a light source. If you were to instantaneously remove that light source, would the room still be lighted?
If yes, if an object and the light source were previously present the room, and were to be instantaneously removed, would the room be reflecting scattered images of that object?
If yes, if we were capable of completely absorbing the remaining photons, can we potentially decipher what the object was?
Again if so, can this ever be used in a real life situation, like solve a crime scene by using remaining photon in the room?
(Sorry if I am not using the correct terms; Amateur hour over here and I'm just really curious about this.)

If there is nothing inside that is not 100% reflective, the light would stay inside. If you want to call that "lighted"... well, a question of definition.

It would become unrecognizable in microseconds due to all the reflections.

We don't have 100% reflective rooms. The light vanishs within less than a microsecond.
