Homework Help Overview
The problem involves determining the slit separation in a double-slit apparatus using the wavelength of light from gaseous mercury and the angle of the fifth dark fringe.
Discussion Character
- Exploratory, Assumption checking, Mathematical reasoning
Approaches and Questions Raised
- The original poster attempts to apply the equation d sin(theta) = m * lambda to find the slit separation but encounters difficulties with the calculations. Some participants suggest reviewing the calculations and converting angles to radians. Others question the appropriateness of the equation for dark fringes, proposing an alternative equation for dark fringe positions.
Discussion Status
The discussion includes attempts to clarify the calculations and assumptions regarding the use of radians versus degrees. Participants are exploring different interpretations of the problem, particularly regarding the equation for dark fringes. There is no explicit consensus, but guidance has been offered regarding the angle conversion and the correct application of the equation.
Contextual Notes
Participants note the need to convert the angle from degrees to radians and discuss the implications of using the correct equation for dark fringes, indicating potential misunderstandings in the setup of the problem.
