Which properties of photons carry info on size,width,height?

Click For Summary
SUMMARY

The discussion centers on the properties of photons and their role in conveying information about physical dimensions such as distance, size, and surface characteristics. It emphasizes that understanding these properties requires a foundational knowledge of classical electromagnetic (EM) waves rather than focusing solely on photons. Key concepts include the interaction of multiple EM waves with materials and the optical systems used for detection. The recommendation is to study geometrical optics, which covers essential principles like specular and diffuse reflection.

PREREQUISITES
  • Classical electromagnetic wave theory
  • Geometrical optics principles
  • Understanding of specular and diffuse reflection
  • Basic knowledge of optical systems and image formation
NEXT STEPS
  • Study geometrical optics to understand light gathering and focusing methods
  • Explore the principles of specular and diffuse reflection in detail
  • Research the interaction of electromagnetic waves with different materials
  • Learn about optical systems used for light detection and imaging
USEFUL FOR

Students and professionals in physics, optical engineering, and anyone interested in understanding the relationship between light properties and physical dimensions of objects.

I know when we see an object then the frequencies of photons reflected from the object carry the information about the colors. Frequencies of visible spectrum helps us to visualize colors. However which properties of photons help us to estimate distance,speed,size,width,height,depth, plainness or roughness of the surface etc. ?

Honestly the best thing you could do is to forget about photons for the time being and focus on classical EM waves. You need to understand concepts in terms of EM waves before you can understand them in terms of photons anyways.

None of these can be explained in terms of single photons or single EM waves. The ability to estimate distance, speed, size, etc is the result of the interaction of many EM waves with both the material/object in question and the optical system used to focus and detect the light. I'd start by looking into geometrical optics, which explains the various methods of how light is gathered and focused into an image and includes things like specular and diffuse reflection. That should provide you with enough information to answer most of these questions yourself. I don't mean to handwave you away, but what you're asking for is beyond my ability to explain in a forum thread.
