The electric and magnetic field oscillate in perpendicular directions. The vector product of the electric field and the magnetic field gives the direction of propagation of the wave. The electric and magnetic fields are sinusoidal. These electric and magnetic field carry energy and momentum. Waves exhibit Reflection Refraction Interference Diffraction Polarization but remember Speed of light is very fast.
Wavelengths are very short.
How does the incident angle compare to the reflected angle. If we can find a relationship between q 1 and q 1 ' then we also have a relationship between q i and q r . The angle of incidence equals the angle of reflection. All of the incident light will be reflected back into the material. This phenomena is called total internal reflection.
