How would you convert visible light to infrared or microwave

Click For Summary
SUMMARY

The discussion centers on the conversion of visible light to infrared or microwave light. Key methods include using objects that absorb visible light and subsequently radiate heat as infrared, as well as employing optical downconverters. The cosmic microwave background radiation serves as a natural example of this phenomenon. Practical home applications are limited, but painting surfaces black can enhance absorption efficiency.

PREREQUISITES
  • Understanding of light absorption and thermal radiation
  • Familiarity with optical downconversion techniques
  • Basic knowledge of the electromagnetic spectrum
  • Awareness of materials that enhance light absorption
NEXT STEPS
  • Research optical downconverters and their applications
  • Explore materials that maximize light absorption for infrared conversion
  • Study the principles of thermal radiation and heat transfer
  • Investigate natural phenomena related to cosmic microwave background radiation
USEFUL FOR

Physicists, materials scientists, and engineers interested in photonics and energy conversion technologies.

Is it possible to convert light in the visible spectrum to infrared or microwave light. What processes would be used to do this?

Thanks,

EJ

Although you can't do this at home, cosmic microwave background radiation is an example of this actually happening in nature.
 
Paint whatever black.
