Examples of electromagnetic wave in the following topics:
-
- Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.
- The creation of all electromagnetic waves begins with a charged particle.
- Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.
- These and many more such devices use electromagnetic waves to transmit data and signals.
- Electromagnetic waves are a self-propagating transverse wave of oscillating electric and magnetic fields.
-
- Maxwell's prediction of the electromagnetic force was confirmed by Hertz who generated and detected electromagnetic waves.
- This loop also had a gap across which sparks were generated, giving solid evidence that electromagnetic waves had been received.
- The propogation of an electromagnetic wave as predicted by Maxwell and confirmed by Hertz.
- The apparatus used by Hertz in 1887 to generate and detect electromagnetic waves.
- An RLC circuit connected to the first loop caused sparks across a gap in the wire loop and generated electromagnetic waves.
-
- Electromagnetic waves have energy and momentum that are both associated with their wavelength and frequency.
- Electromagnetic radiation can essentially be described as photon streams.
- In other words, there were only certain energies an electromagnetic wave could have.
- Momentum is classically defined as the product of mass and velocity and thus would intuitively seem irrelevant to a discussion of electromagnetic radiation, which is both massless and composed of waves.
- Relate energy of an electromagnetic wave with the frequency and wavelength
-
- Radio waves are EM (Electromagnetic)waves that have wavelengths between 1 millimeter and 100 kilometers (or 300 GHz and 3 kHz in frequency).
- Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light .
- Like all other electromagnetic waves, radio waves travel at the speed of light.
- Electromagnetic waves also broadcast television transmission.
- The electromagnetic spectrum, showing the major categories of electromagnetic waves.
-
- Similarly we find that electromagnetic waves carry energy.
- Electromagnetic radiation (EMR) carries energy—sometimes called radiant energy—through space continuously away from the source (this is not true of the near-field part of the EM field).
- Electromagnetic waves can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields .
- The photon is the quantum of the electromagnetic interaction, and is the basic "unit" or constituent of all forms of EMR.
- Electromagnetic waves can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields.
-
- Light is an example of a transverse wave.
- A ripple on a pond and a wave on a string are easily visualized transverse waves.
- Transverse waves are waves that are oscillating perpendicularly to the direction of propagation.
- Examples of transverse waves include seismic S (secondary) waves, and the motion of the electric (E) and magnetic (M) fields in an electromagnetic plane waves, which both oscillate perpendicularly to each other as well as to the direction of energy transfer.
- Therefore an electromagnetic wave consists of two transverse waves, visible light being an example of an electromagnetic wave.
-
- Electromagnetic waves are typically described by any of the following three physical properties: the frequency (f) (also sometimes represented by the Greek letter nu, ν), wavelength (λ), or photon energy (E).
- Whenever electromagnetic waves exist in a medium with matter, their wavelength is decreased.
- Generally, electromagnetic radiation is classified by wavelength into radio wave, microwave, terahertz (or sub-millimeter) radiation, infrared, the visible region we perceive as light, ultraviolet, X-rays, and gamma rays.
- For example, SLF radio waves at 60 Hz may be received and studied by astronomers, or may be ducted along wires as electric power, although the latter is, in the strict sense, not electromagnetic radiation at all.
- Calculate frequency or photon energy, identify the three physical properties of electromagnetic waves
-
- A sea wave is an example of a wave in which water molecules are moving up and down as waves propagate towards the shore.
- Waves transfer energy not mass.
- While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse.
- For example, acoustics is distinguished from optics in that sound waves are related to a mechanical rather than an electromagnetic (light) wave transfer caused by vibration.
- A brief introduction to the wave equation, discussing wave velocity, frequency, wavelength, and period.
-
- The manner in which solar energy travels is described as waves.
- The electromagnetic spectrum shows several types of electromagnetic radiation originating from the sun, including X-rays and ultraviolet (UV) rays.
- Short, tight waves carry the most energy.
- It takes little effort by a person to move a rope in long, wide waves.
- The wavelength of a single wave is the distance between two consecutive points of similar position (two crests or two troughs) along the wave.
-
- Waves are disturbances; they are changes in something - the surface of the ocean, the air, electromagnetic fields.
- Most kinds of waves are transverse waves.
- Sound waves are longitudinal waves.
- A mathematical description might be that in longitudinal waves, the waves (the disturbances) are along the same axis as the direction of motion of the wave; transverse waves are at right angles to the direction of motion of the wave.
- In water waves and other transverse waves, the ups and downs are in a different direction from the forward movement of the wave.
