Question: `qPrinciples of Physics and General College Physics Problem 24.54: What is Brewster's angle for an air-glass interface (n = 1.52 for glass)?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

Brewster’s angle is the smallest angle theta _p of incidence at which light is completely polarized. This occurs when tan (theta_p) = n2/n1, where n2 is the index of refraction on the other side of the interface. For an air glass interference, n1=1, so tan (theta_p) =n2/n1, the index of refraction of the glass. We get tan (theta_p)=1.52 so then theta_p =arctan(1.52). This is calculated as the inverse tangent of 1.52 using the 2d function- tan combination on a calculator we obtain theta_p=56.7 degrees.

Given Solution:

`aBrewster's angle is the smallest angle theta_p of incidence at which light is completely polarized. This occurs when tan(theta_p) = n2 / n1, where n2 is the index of refraction on the 'other side' of the interface.

For an air-glass interface, n1 = 1 so tan( theta_p) = n2 / 1 = n2, the index of refraction of the glass. We get

tan(theta_p) = 1.52 so that

theta_p = arcTan(1.52). This is calculated as the inverse tangent of 1.52, using the 2d function-tan combination on a calculator. WE obtain

theta_p = 56.7 degrees, approximately.
