Optical path difference caused by double slit

Click For Summary

Homework Help Overview

The discussion revolves around the optical path difference in a double slit experiment when one slit is covered with a thin glass. Participants are exploring the effects of this setup on the observed fringe pattern.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the reasons behind the movement of the fringe pattern toward a specific direction when light passes through the thin glass. There is an exploration of the phenomena occurring when light transitions between media, particularly focusing on refraction.

Discussion Status

The discussion is ongoing, with participants sharing their thoughts on the effects of refraction and prompting further exploration of additional phenomena that may occur when light passes through different media. There is no explicit consensus yet, as various interpretations are being considered.

Contextual Notes

Participants are discussing the implications of covering one slit with a thin glass and the resulting changes in the interference pattern, indicating a focus on the assumptions related to light behavior in different media.

What do you think might be going on here?
 
Only The light originate from s2 will pass thru the thin glass.
