+// Scilab Code Ex5.6 : Brewster angle at the boundary between two materials : Page-114 (2010)

+C = 52;    // Critical angle for total internal reflection at a boundary between two materials, degrees

+// From Brewster's law, tand(i_B) = 1_mu_2

+// Also sind(C) = 1_mu_2, so that

+// tand(i_B) = sind(C), solving for i_B

+i_B = atand(sind(C));    // Brewster angle at the boundary, degrees

+printf("\nThe Brewster angle at the boundary between two materials = %2d degrees", i_B);

+

+// Result 

+// The Brewster angle at the boundary between two materials = 38 degrees
