Talk:Interference
From Academic Kids
I'd like to see information here regarding the phenomena of rainbow-like interference patters as created by a continuum light source repeatedly refracting in a thin film, such as soap bubbles or oil on water. If this isn't the right article for the discussion, where would be? --zandperl 01:07, 9 Mar 2004 (UTC)
I suggest that effort should be devoted to the subject of interference at the level of
words
two languages
memory and thinking
intent and expression
etc.
in other words in more lay areas of common experience of living

How an interference pattern is produced
In the article it is stated:
- Light beams that can produce interference patterns are called "coherent," and have all of their photons' phases aligned with each other.
This is incorrect. Incoherent light will produce an equally sharp interference pattern. White light will give an unsharp interference pattern, as the different wavelengths have different diffraction.
The famous Michelson-Morley experiment was conducted well before lasers were available. It must have tested the e~xperimentors ingenuity to obtain a lightsource that is both close to monochromous, and sufficiently bright to get a good reading.
According to quantum electrodynamics, each photon interferes only with itself. Laserlight is an exception to that: because of the cascading way they are produced laser photons are mutually connected in deeper ways than light from normal origin. --Cleon Teunissen | Talk 19:51, 22 Mar 2005 (UTC)
