How big is a visible photon?

In this video I discuss the behavior of photons/electromagnetic waves especially the aspect of interference.

 

The current video not only exposes the flaw, but presents a better explanation. 

  • 0:00 General Intro 
  • 0:47 What do others say? 
  • 1:21 About wavelength and size
  • 2:10 Interference in light 
  • 3:08 Electromagnetic waves and detection
  • 5:25 Things that make you go Hmmm… 
  • 7:36 New experiment and setup 
  • 10:23 Calculation of single photon level (boring) 
  • 11:59 Result of the new experiment 
  • 12:41 Discussion of the result 
  • 16:29 About „shot noise“ 
  • 17:16 EM field strength and probability of detection 
  • 19:18 So how big is it then? 
  • 20:02 Deleted scene

The scientific explanation is actually very mathematical and way more complex: https://en.wikipedia.org/wiki/Degree_….
