As light leaves a slower medium and enters a faster one, it accelerates and is redirected away from the normal. By convention, the angles involved in reflection and refraction are measured with respect to the normal at the point of contact.

All three components are in the same plane [there are some exceptions]. In the above illustration, the plane of incidence is the paper.

Displacement and Polarization Energy displacement in waves can be either longitudinal or transverse with respect to the direction of travel.

Longitudinal waves such as sound and seismic waves, are displaced in the direction of travel. Transverse waves such as radio and water waves are displaced at right angles to the direction of propagation. Light travels as a TEM wave, having electric and magnetic fields perpendicular to the direction of travel.

If there is no particular reason for the electrical fields of light to favor any particular orientation, the field of the waves are directed polarized at any angle perpendicular to the direction of propagation. This is the case with sunlight.

The combined effect of many simultaneous waves is the vector sum of all of their components. This is known as the superposition principle. This principle holds true with all forms of waves, including light.

Fundamentals of Optical Fiber Communications

The reason is simple: they do average out, but, since this averaging is not exact, but is a random one, the laws of statistics hold. So, when we sum N random fields which oscillate, say, from minus to plus one, we expect that the sum is of the order of the square root of N, which can be enormously less than N, but is not zero.

And, since the energy the intensity of light is proportional to the square of the electric field, we have that the mean energy of the sum is just N times the individual energies, which is precisely what we expect.

A cancellation or enhancement effect do occur, but to observe it the light must be coherent.

Traditionally coherent light was created by passing light from some distant source through a small hole.
