The discussion focuses on the Fabry-Perot problem, specifically demonstrating that increasing the distance L between two mirrors by \(\lambda/2\) is sufficient to scan the transmission peak over one Free Spectral Range (FSR). Participants emphasize the importance of understanding the FSR concept and suggest consulting relevant textbooks for detailed explanations. The equation \(D=2L\sqrt{1+v^2/c^2}\) is mentioned as part of the solution approach, although further guidance is requested to clarify the relationship between distance and FSR.
PREREQUISITESStudents and researchers in optics, particularly those studying wave interference and resonant cavities, will benefit from this discussion. It is also valuable for anyone looking to deepen their understanding of Fabry-Perot interferometry and its applications.
