An electromagnetic wave can be thought of as propagating electric and magnetic fields. An electromagnetic wave propagates with the electric field and magnetic field perpendicular to each other.
disturbances made up of electric and magnetic fields that do not require a medium for travel.
Waves with both an electric and magnetic component. They are: radio, micro, infra-red, visible light, ultraviolet, X and gamma rays.
Travelling disturbance comprising an electric field and a magnetic field at right angles to each other.
oscillating electric and magnetic fields traveling together through space at a speed of nearly 186,000 mi/300,000 km per second. The (limitless) range of possible wavelengths or frequencies or electromagnetic waves, which can be thought of as making up the electromagnetic spectrum, includes radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
These waves are not sound, although people often use them to transmit sound information such as using radio waves. These all have the same speed, which is (The speed of light). Light, Microwaves and Infa-red are also part of the electromagnetic spectrum.
All matter absorbs and emmits radiation covering a broad band of frequencies and wavelengths. This electromagnetic radiation has the velocity of the speed of light (2.998 x 108 ms-1) and arises from the vibrating electric charges in atoms and bonds. The range of wavelengths, also known as the electromagnetic spectrum is shown below
Electromagnetic radiation which moves from the source through space in the form of electromagnetic waves. Where electric appliances are concerned, the limits of transmission of these emissions are defined by international standards.
Electromagnetic waves form a continuous spectrum of which visible light is only a small part. Gamma rays, X-rays, microwaves, and radio waves are also electromagnetic waves. They are also known as EM waves. Electromagnetic Waves
A wave of energy having a frequency within the electromagnetic spectrum and propagated as a periodic disturbance of the electromagnetic field when an electric charge oscillates or accelerates.
Waves of the electromagnetic field that are propagated in space at the speed of light, approx. 300,000 km per second.
A wave propagated through space by simultaneous periodic variation in the electric and magnetic field intensity at right angles to each other and to the direction of propagation. The electromagnetic spectrum includes radio waves, microwaves, infrared, visible and ultraviolet radiation, X-rays, gamma rays and cosmic rays.
Modified currents and voltages generate oscillation of the electrical and magnetic field which propagates in a vacuum.
The combination of electricity and magnetism which carries radio transmissions though Free Space.
Another term for light. Light waves are fluctuations of electric and magnetic fields in space.
waves propagated through the simultaneous periodic intensity variation of an electric and magnetic fields. Electromagnetic waves propagate through free space without any medium. Electromagnetic waves include radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays and gamma rays.
A wave propagating as a periodic disturbance of the electric and magnetic fields and having a frequency in the electromagnetic spectrum; the means by which energy is transmitted from one place to another.
