SUMMARY

The discussion centers on the calculation of light reflections between two mirrors placed 10 feet apart. It concludes that light would reflect approximately 98,208,000 times per second if 100% of the light is reflected. However, the distance for two reflections is actually 20 feet, which leads to a potential adjustment in the calculation. The speed of light in mirror glass is noted as 0.66c, while in air it is 0.9997c, emphasizing the need for recalculating based on the medium of reflection.

PREREQUISITES
  • Understanding of the speed of light and its variations in different media.
  • Basic knowledge of optics, specifically reflection principles.
  • Familiarity with the concept of light travel distance and time calculations.
  • Awareness of the effects of a vacuum on light speed.
NEXT STEPS
  • Calculate light reflection rates in various mediums, including vacuum and glass.
  • Explore the principles of optics, focusing on reflection and refraction.
  • Investigate the implications of light speed variations in different environments.
  • Learn about the mathematical modeling of light behavior in physics.
USEFUL FOR

Physicists, optics enthusiasts, and anyone interested in the behavior of light and its reflections in different media.

If you placed two mirrors facing each other exactly 10 feet apart (assuming 100% of the light is reflected), I figure light would pass back and forth between the mirrors ~98,208,000 times in 1 second. Or would it be half of that because the distance for two reflections traveled would actually be 20 feet? This one is hurting my brain..

Apologies for the randomness of this question but it came to me last night and has been bugging me since.

98 mil 1 way, 49 mil 2 ways.
 
Is this in a vacuum ?
Either way, the speed of light in the mirror glass is 0.66c, the speed of light in air is 0.9997c.
Recalculate !
