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.
-
- An antenna is a device that converts electric power into radio waves, and vice versa.
- As a consequence, visible light and radio waves should share common characteristics.
- In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves).
- In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals.
- A common car antenna that converts electric power in the air into 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.
-
- 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.
-
- Wave–particle duality postulates that all physical entities exhibit both wave and particle properties.
- Wave–particle duality postulates that all physical entities exhibit both wave and particle properties.
- In 1861, James Clerk Maxwell explained light as the propagation of electromagnetic waves according to the Maxwell's equations.
- Black body radiation: In 1901, to explain the observed spectrum of light emitted by a glowing object, Max Planck assumed that the energy of the radiation in the cavity was quantized, contradicting the established belief that electromagnetic radiation is a wave.
- De Broglie's wave (matter wave): In 1924, Louis-Victor de Broglie formulated the de Broglie hypothesis, claiming that all matter, not just light, has a wave-like nature.
-
- Superposition occurs when two waves occupy the same point (the wave at this point is found by adding the two amplitudes of the waves).
- Waves are most commonly described by variations in some parameter through space and time—height in a water wave, pressure in a sound wave, or the electromagnetic field in a light wave.
- A stereo has at least two speakers creating sound waves, and waves can reflect from walls.
- All these waves superimpose.
- In this figure, the two waves add together and cancel out leaving no wave.
