Homework Help Overview

The discussion revolves around the properties of light as they relate to the colors observed in soap bubbles, specifically focusing on the concepts of wavelength and interference patterns.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between wavelength and color visibility in soap bubbles, questioning how thickness affects interference and color perception.

Discussion Status

There is an ongoing exploration of how varying thickness in soap bubbles leads to different colors being visible. Some participants provide insights into constructive and destructive interference, while others seek clarification on the implications of wavelength.

Contextual Notes

Participants note that the thickness of the soap bubble can vary significantly, which may influence the colors observed. There is also mention of the conditions under which interference occurs, particularly regarding the relationship between thickness and wavelength.

which of the following colours would you expect to see near the bottom of a soap bubble, red or blue?...i think red is... because it has longer wavelength?

Maybe. I'd be more convinced if you explain what wavelength has to do with it.
 
if the thickness of the soap bubble is much smaller than the wavelength of light, the result is destructive interference (dark color). the thickness required to produce constructive interference for red is larger than that required for blue. ...
 
but we see all the rainbow colors in soap bubble because thickness of the bubble varies...the bottom of the bubble is thicker...therefore we see red at the bottom/??

Not bad. Though if the thickness is much smaller than wavelength of light then you won't see much interference at all. But I'll take that explanation.
