Talk:Newton's rings

message: *The figure for "Simulation of Newton Rings under reflected light of different wavelength" has the wrong wavenumbers displayed. They should be 10 times larger. LDCorey (talk) 05:05, 1 April 2014 (UTC)
thread_title: Various comments

message: It should be noted that Newton thought that light consists of particles rather than waves. So I'm surprised that its named after Newton (I knew the phenomenon of interference rings but I hadn't heard this name for this special case before I came across this article). 193.154.191.21 01:37, 16 February 2006 (UTC)
replies: text: What 'Newton thought' was not constant. He tried at one time to make a wave theory work (as in Opticks, Question 13). He even realised that red had a longer wavelength than violet. In the end he gave up the wave theory for the particle theory . --Heron 19:34, 16 February 2006 (UTC)
replies: text: I read somewhere that Newton gave the explanation that the particles of light were disturbed by the glass and vibrated.  That is like the explanation of the neutral kaons,  and , oscillating from one to the other after passing through a target.  He just had the wrong particle.  David R.

text: It would be good to say what Newton wrote about the rings, in Opticks, and later when he swung away from waves towards particles. If not here, maybe in some other summary of Newton's theories of light ? - Rod57 (talk) 11:23, 20 May 2021 (UTC)
thread_title:  Newton's notion of light 

message: Don;t know if this would be relevant, or if my understanding is flawed so thought I should post here first.  Am I correct in my understanding that Newton's Rings are a form of a diffraction pattern?  Just wondering if anyone else thinks this article might be enhanced by a brief mention of that or a link to the wiki article on diffraction. :) Weenerbunny 17:40, 7 July 2006 (UTC)
replies: text: Weenerbunny, Diffraction patterns are formed by interference of light waves scattered by narrow slits or lines, Newton's Rings are formed by interference of light waves reflected from different surfaces. Same effect, but different reasons why waves follows the slightly different path lengths that result in light and dark zones - constructive and destructive interference. - Gil johnson 22:18, 29 April 2007 (UTC)

message: The equation is off. I will change it ASAP, but I am not very good at the formulas. Here is the link to the page, if anyone else wants to change it, you may. http://www.fas.harvard.edu/~scdiroff/lds/LightOptics/NewtonsRings/NewtonsRings.html
It is the second equation, the one for the mth ring.

message: Newton's rings are a common annoying problem when scanning transparencies. I don't have the time or expertise to explain the solution, but I've seen some scanner operators spread a liquid gel onto a tranny before taping it down to a drum scanner, for example. The other option is to mount a tranny in a special mounting bracket so that the tranny sits in free air instead of next to glass when it's inside a scanner. Dave Laird 06:52, 16 February 2007 (UTC)

message: Would it be accurate to say that if the two surface come in contact, the central ring is where the surfaces are optically coupled? —Ben FrantzDale (talk) 20:28, 29 July 2008 (UTC)

message: According to Richard Feynman, Newton's rings are not caused by wave interference, and instead are caused by quantum effects. He discusses how Newton was right about light being made of particles, but for the wrong reason. Newton's rings in particular are the main example in his first popular lecture on Quantum Electrodynamics: https://www.youtube.com/watch?v=xdZMXWmlp9g
(All four lectures can be found here: http://www.vega.org.uk/video/subseries/8. These lectures were later turned into the book "Quantum Electrodynamics.")
In essence, one still gets the Newton Ring effect even when dealing with a single photon. Currently, this whole article is about how a wave approximation of light can lead to Newton's Rings... which makes intuitive sense until you get to the single photon level. And yes, it's useful to think about light as having a mathematical wave that precedes it. But I will suggest that we need a whole section about how Newton's Rings happen with photons. Without this, it's like saying DeYoung's double slit experiment happens because light hitting the two slits is analogous to waves hitting a sandbar with two openings. We know this isn't true.
