How big is a visible photon?
Quote
This video is actually not about photon size but about coherence length. In this video I discuss the behavior of electromagnetic radiation, especially the aspect of interference. The experiment shows that there is no such thing as individual photons in EM radiation. The photon only exists as an energy exchange between radiation and matter.
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?

At 3:08 the Electric and Magnetic field components have been swapped accidentally.
