Talk:Soap bubble/to do


 * Although the two figures explaining interference using two red rays and two blue rays are correct by themselves, they should not be used to explain the colors we see on a bubble. In real life, ray 1 and ray 2 are rarely coherent. Their phase differences are random so on average ray 1 and ray 2 do not interfere with each other. As a result, they do not create colors. The colors on a bubble are mainly a result of the interference between the two reflected rays from the same incident ray (ray 1 or ray 2).
 * Somebody please change the 2nd column for reflection and interferences section. The red light should be 180 degrees out of phase instead of being in phase.  The one ray on the outside of the bubble goes through hard reflection.
 * what are they made of?
 * Lead section is inadequate.
 * The "How to make soap bubbles" section, by its very nature, reads like a "how to", and does not fit in an encyclopædia.
 * There are only a small handful of references, none of which are in-line. From the names of the references given, it seems unlikely that they would cover all the subject material covered in the article. The references need to be more specific.
 * "See also" and "External links" sections contain descriptions of links in a very un-encyclopædic manner.
 * Several sections do not sit right as sections: for example "Coloured bubbles" and "Structure" are (almost) single paragraphs.
 * Mix of BrE and AmE.
 * The whole thing is quite poorly written: the English is not up to standard. Take for example the lead: "Soap bubbles usually last for only a few moments and then burst either on their own or on contact with another object." - there are no commas in this sentence, where they are required. This writing continues throughout.
 * The captions of the photos are poorly written and not informative.
 * The description of interference is still not quite correct. As far as I can tell as of 10/19/2006, the 180 degree phase shift in the wave reflected from the first interface (air to water) is not mentioned in the main article.  This is mentioned in the discussion page, but I guess never made it to the article?  There are drafts on the discussion page of improved figures, but these too are not quite correct.  The 180 degree phase shift is a very important part of the effect!-Skoch3
