SUMMARY

The discussion focuses on calculating the Brewster angle for the transition between air and glass. The formula used is θB = tan-1(n2/n1), where n1 is the refractive index of the first medium and n2 is that of the second. For air to glass, n1 is 1 and n2 is 1.45, yielding a Brewster angle of approximately 42 degrees. Conversely, for glass to air, n1 is 1.45 and n2 is 1, resulting in a Brewster angle of about 48.6 degrees. The calculations provided are confirmed as correct.
