Electromagnetic waves (those that can transmit their energy through a vacuum) have both an electric and a magnetic component. They are created by a vibration of charged particles. When passing through a medium, they are propagated by absorption and reemission of the wave energy by the atoms in the material.

∙ 13y agoElectromagnetic (EM) waves propagate in transverse modes. The common mode used to describe EM propagation is the TEM, or Transverse ElectroMagnetic, mode, where neither the electric field nor the magnetic field of the wave is in the direction of propagation. In practice, however, this rarely happens, and one finds EM waves travelling in a hybrid mode. Read more about EM modes at the link I provided.

Is color generated by electromagnetic waves?
No, colour is generated by the energy state of an electron in a bond. When we see objects of different colors, it is because our retinas are being activated by electromagnetic waves of different wavelengths (or frequencies, if you prefer). Or at least because our brains think they are receiving such a signal.
What is the least value of frequency of an electromagnetic wave that exist in the universe?
Geomagnetic waves are thought to be the lowest frequency (and, therefore, the longest wavelength) electromagnetic waves in the universe. They are generated by movements in planetary structures that modulate a planet's magnetic field to create the wave. Certainly lower frequency electromagnetic waves could be generated, but they would be artificial. A link is provided for some useful information.
What is the reason for ultrasonic waves not being in the form of electromagnetic waves?
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.
Sound is not part of the electromagnetic spectrum because?
because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....
The energy of visible light transported by electromagnetic waves are what type of waves?
electromagnetic waves are longitudinal (like a slinky).
What waves are propagated by electromagnetism?
Electromagnetic waves.
Can electromagnetic waves be propagated through solid liquid and gas products?
yes
What is seismec waves?
Seismic waves are the vibration generated by an earthquake, explosion, or similar phenomenon and propagated within the Earth or along its surface.
What are subtomic particles of energy and matter propagated bl electromagnetic waves?
protons, nuetrons, electronsNot protons, but Photons.
How are em waves different from mechanical waves?
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
What is meant by electromagnetic radiation?
electromagnetic radiation is caused by radiant energy generated by accelerating electrons of photons travelling as waves.
What do radio waves propagated through the interaction of?
radio waves are propagated through the interaction of
Do waves occur only in water?
Waves can occur in any liquid. Waves can also be propagated through rock, during an earthquake, and the same mathematics that describes water waves also describes waves in electromagnetic energy such as light or radio.
Is color generated by electromagnetic waves?

Or at least because our brains think they are receiving such a signal.
What is the definition of em waves?
Electromagnetic waves are force fields generated by vibrating, electrically charged particles. They are described mathematically by the Maxwell Equations.
What is the least value of frequency of an electromagnetic wave that exist in the universe?

What is the difference between electrmagnetic waves and lasers?
Electromagnetic waves are generated through frequency oscillations which usually involve a coil of wire or in an extension such as a transmitting antenna. Lasers are light, formed in a coherent beam and generally don't exhibit electromagnetic waves.
