To solve for the coherence length numerically, we first need the general formula and the given parameters. The coherence length (L_c) is defined in optics as the length over which a light wave (or any wave) maintains a predictable phase relationship. For a source with a central wavelength (\lambda) and spectral width (\Delta \lambda), the coherence length is given by: [ L_c = \frac{\lambda^2}{\Delta \lambda} ] Let’s
