// Example no. 1.8
// To calculate a)magnitude of the wave vector of the refracted wave b)x-component and z-component of the wave vector
// Page no.26

//Given data
n1=1; // Refractive index of air
n2=1.45; // Refractive index of slap
theta1=%pi/3; // Angle of incidence
lambdam=1.0889*10^(-6); // Wavelength in medium
theta2=asin(sin(theta1)/n2); // Angle of refraction
// a)To calculate magnitude of the wave vector of the refracted wave
k=((2*%pi)/lambdam); // Wavenumber
// Displaying the result in command window
printf('\n Magnitude of the wave vector of the refracted wave is same as wave number = %0.2f X 10^6 m^-1',k*10^(-6));
// b)To calculate x-component and z-component of the wave vector
kx=k*sin(theta2); // x-component of the wave vector
kz=k*cos(theta2); // z-component of the wave vector
// Displaying the result in command window
printf('\n z-component of the wave vector = %0.2f X 10^6 m^-1',kz*10^(-6));
printf('\n x-component of the wave vector = %0.2f X 10^6 m^-1',kx*10^(-6));
// The answer is varrying due to round-off error
