Homework Help Overview

The discussion revolves around the application of a formula related to visible wavelengths and thin films, specifically focusing on the conditions for constructive and destructive interference.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the use of the equation 2nt = (m[+.5])λ, questioning the appropriate value for m to achieve specific interference conditions and whether to include the [+.5] term.

Discussion Status

Some participants have provided insights regarding the selection of m and its implications for the interference pattern, while others are seeking further clarification on the application of the formula.

Contextual Notes

There is a focus on understanding the conditions for minimum index and the distinction between constructive and destructive interference, with participants questioning how these concepts apply to their specific problem.

If anyone could help me out it would be greatly appreciated.

2nt = (m[+.5])[tex]\lambda[/tex]

What's the problem? You seem to have the right equation on hand.
 
o yea sorry, the further question was;

what would I use for m to achieve the minimum index? 1?

As well, would I use the [+.5] or not, meaning destructive vs constructive.

Those 2 were my detailed questions.
 
anyone?
 
M would have to be the smallest possible integer without the right-hand-side being less than or equal to 0.
