Considering a monochromatic plane wave of optical frequency f (light of vacuum wavelength λ has a frequency of f = c/λ where c is the speed of light), let us take the direction of propagation as the z axis.
It is possible to transform unpolarized light into polarized light. Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization. There are a variety of methods of polarizing light. The four methods discussed on this page are:
Basic properties of waves: Amplitude, wavelength, and frequency. As you might already know, a wave has a trough (lowest point) and a crest (highest point). The vertical distance between the tip of a crest and the wave’s central axis is known as its amplitude.
The axis of a polarizing filter is the direction along which the filter passes the electric field of an EM wave (see Figure 27.40 ). Figure 27.39 The slender arrow represents a ray of unpolarized light. The bold arrows represent the direction of polarization of the individual waves composing the ray.
When the light polarization is aligned with what we define as the polarizing axis of the substance, then little of the light is absorbed by the substance (i.e. the substance is transparent to this light), while if the light is polarized perpendicular to the polarizing axis, then virtually all of the light is absorbed.
The most common source of polarized light is a laser. Depending on how the electric field is oriented, we classify polarized light into three types of polarizations: Linear polarization: the electric field of light is confined to a single plane along the direction of propagation (Figure 1) .
