Homework Help Overview
The discussion revolves around a problem related to Young's double slit experiment, specifically focusing on the interference pattern produced by red light with a wavelength of 700nm, following an initial setup using blue light of 450nm. The original poster is attempting to determine how many red fringes will be visible on a screen placed 1.5m from the slits.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants are questioning the validity of the calculations presented by the original poster, particularly the use of sin(90) in the context of maximum fringe order. There is also discussion about the implications of the screen size and its relation to the number of visible fringes.
Discussion Status
The discussion is ongoing, with participants exploring various interpretations of the problem and questioning the completeness of the original question. Some guidance has been offered regarding the potential need to clarify the dimensions of the screen to accurately determine the number of visible fringes.
Contextual Notes
There are indications that the original question may be incomplete or contain errors, particularly regarding the screen dimensions and the relevance of the blue light setup. Participants are encouraged to verify the details provided in the problem statement.
