SUMMARY

The discussion confirms a definitive quantitative relationship between luminous intensity and photon flux for monochromatic light. It states that if luminous intensity (I) is measured in Joules per square meter per second, and each photon carries energy defined by Planck's constant (h) multiplied by frequency (f), the number of photons (N) per square meter per second can be calculated using the formula N = I/(h*f). This establishes a clear mathematical connection between these two concepts in photonics.

PREREQUISITES
  • Understanding of luminous intensity and its units (Joules/(m^2-sec))
  • Familiarity with Planck's constant (h) and its significance in quantum mechanics
  • Knowledge of photon energy and frequency relationship (E = h*f)
  • Basic principles of photonics and light behavior
NEXT STEPS
  • Research the implications of luminous intensity in lighting design
  • Explore the applications of Planck's constant in quantum physics
  • Learn about the calculation of photon flux in various light sources
  • Investigate the role of frequency in determining photon energy
USEFUL FOR

Physicists, optical engineers, and anyone involved in the study of light and photonics will benefit from this discussion, particularly those focusing on the quantitative analysis of light properties.

Is there any quantitative relationship between luminous intensity of monochromatic light and flux of photons(number of photons/(area*second)) ?
 
Physics news on Phys.org
Yes, there is. If I have a certain intensity of light I in Joules/(m^2-sec), and each photon carries an energy equal to h*f, then the number of photons per m^2 per sec is just:

N = I/(h*f) photons/(m^2-sec)
