Question: Assume that at a given frequency the opacity of the stellar plasma at the surface of a given star is dominated by Thomson scattering. Estimate the depth (in cm) of the atmosphere that is visible to an outside observer at that frequency, while assuming that the electron density in this region is constant and equal to 1016 cm3.
