The nature of such electromagnetic waves is beyond the scope of The Physics Classroom Tutorial.For our purposes, it is sufficient to merely say that an electromagnetic wave is a transverse wave that has both an electric and a magnetic component.
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. 9.2.1 Arbitrary Polarization Case and Axial Ratio The axial ratio (AR) is an important gure of merit for designing CP antennas (antennas Recall that in an isotropic medium, electromagnetic field travelling along z …
the accelerated charge. A light wave is an electromagnetic wave that travels through the vacuum of outer space. Polaroid materials, invented by the founder of Polaroid Corporation, Edwin Land, act as a polarizing slit for light, allowing only polarization in one direction to pass through.
The frequency of oscillation of the electromagnetic wave naturally equals to frequency of oscillation of the charge.
Light is an electromagnetic wave in which electric and magnetic field are varying in time and space at right angle to the direction of the propagation of the wave. In the year 1865, Maxwell predicted the electromagnetic waves theoretically.
The polarisation of an electromagnetic wave indicates the plane in which it is vibrating.

To talk about the polarization of an electromagnetic wave, it's easiest to look at polarized light. The Sun and many other light sources produce waves that are randomly polarized (see Figure 4).
0 and B~0 are called the polarization vectors for the electric and magnetic fields. Wave polarization occurs for vector fields. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave.
In particular, the global description of non-uniformly polar-ized beams has been investigated in detail in the paraxial case (see, for example, [2, 3]). Light is a transverse electromagnetic wave that can be seen by a typical human. Question: Task 2 - Polarization Of Electromagnetic Waves (4 Points] Describe The State Of Polarization Of The Waves Represented By The Following Equations: I. Ey = A Cos(wt – Kx) Ez = A Sin(wt – Kx) II. Light waves are produced by vibrating electric charges.
Polarization, property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way. Ey = A Cos(wt – Kx) Ez = - A Cos(wt – Kx) III. Polarization refers to the direction of oscillation of the electric field in an electromagnetic wave (and because the magnetic field is always perpendicular to the electric field, polarization also determines the direction of oscillation of the magnetic field).
If we confined the vibration of these electric vectors of light waves to the one direction it is called polarization of light.
Description of polarization I Consider an electromagnetic, monochromatic plane wave of angular frequency ω that is propagating in vacuum along a direction that we assume as the z-axis of a right-handed reference system.
This ray-tracing business is known as geometrical optics. A.
Such light is said to be unpolarized because it is composed of many waves with all possible directions of polarization.
