Homework Help Overview
The discussion revolves around the concept of thin film interference, specifically focusing on determining the thinnest film of a coating with a refractive index of 1.43 on glass (with a refractive index of 1.52) that allows for destructive interference of red light (660 nm) reflected from the film.
Discussion Character
- Exploratory, Conceptual clarification, Mathematical reasoning
Approaches and Questions Raised
- Participants explore the relationship between film thickness and wavelength, questioning how the refractive index affects the wavelength of light within the film. There is an attempt to understand the conditions for destructive interference and the significance of the 1/4 wavelength condition.
Discussion Status
Some participants have provided insights into the relationship between the thickness of the film and the wavelength of light, suggesting that the thickness should be 1/4 of the wavelength within the coating. Others express confusion about the concepts involved and seek further clarification.
Contextual Notes
Participants note the challenge of understanding the problem and the definitions involved, indicating a need for clearer explanations of the underlying principles of thin film interference.
