mu = 1.53; // Refractive index of the material from Brewster's law
// As mu = tand(ip), solving for ip
ip = atand(mu); // Polarizing angle, degrees
// But mu = sind(ip)/sind(r), solving for r
r = asind(sind(ip)/mu); // Angle of refraction, degrees
printf("\nThe angle of refraction of the ray = %4.1f degrees", r);
// Result
// The angle of refraction of the ray = 33.2 degrees
