SUMMARY
The discussion focuses on calculating the spectral bandwidth for green light (546.1 nm) and sodium light based on measured coherence length. The coherence length (Lcog) is given as 0.122 mm, which is directly related to the time coherence (tcog) and bandwidth (Δf) through the equation Lcog = c tcog = k (c/Δf), where k is dependent on the spectral shape. The user seeks theoretical values for the spectral width of both green and sodium light to aid in their lab report.
