One can imagine electromagnetic waves as series of very regular waves that travel at an enormous speed, the speed of light. The frequency simply describes the number of oscillations or cycles per second, while the term wavelength describes the distance between one wave and the next.
Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

Electromagnetic radiation is energy transmitted at a fixed velocity through sinusoidally varying electric and magnetic fields. The frequency of variation of this energy, represented by the greek letter ν, is the number of oscillations per second, measured in hertz (hz).
The alteration of spontaneous low frequency oscillations caused by acute electromagnetic fields exposure.
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
Alternating currents; forced oscillations a series circuit may be set into forced oscillation at a driving angular frequency ω d by an external alternating emf (31-28).
Of course, if an oscillation is excited in a compact star, there will be also other mechanisms, most notably gravitational-wave emission, that, together with the electromagnetic ones, will combine to damp the stellar oscillations. 4 for simplicity, we will consider these mechanisms as acting independently and compute in the following sections.

Figure 2: oscillations in a damped harmonic oscillator for various damping constants 2 if β is large enough, particularly if 2 1/ lc the system doesn’t even oscillate any more, it becomes overdamped. This can be useful for situations where you don’t want oscillations in a spring, like for springs on a vehicle’s suspension system.
Visible light is a commonly studied form of electromagnetic radiation, and exhibits oscillating electric and magnetic fields whose amplitudes and directions are represented by vectors that undulate in phase as sinusoidal waves in two mutually perpendicular (orthogonal) planes.
Electromagnetic radiation is a phenomenon that takes the form of self-propagating energy waves as it travels through space (vacuum or matter). The energy waves oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation.
