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.
What else can I help you with?
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.
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.
Waves made by vibrating charges that can travEl without a medium are called?
Electromagnetic waves.
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.
Which is not a type of electromagnetic wave?
Sound waves are not a type of electromagnetic wave. Sound waves are mechanical vibrations that require a medium, such as air or water, to propagate, whereas electromagnetic waves can travel through a vacuum.
What waves are propagated by electromagnetism?
Electromagnetic waves are propagated by electromagnetic fields, composed of oscillating electric and magnetic fields. These waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each of these waves has a specific frequency and wavelength within the electromagnetic spectrum.
Can electromagnetic waves be propagated through solid liquid and gas products?
Yes, electromagnetic waves can be propagated through solids, liquids, and gases. The ability of electromagnetic waves to propagate through these mediums is determined by their properties, such as conductivity and permittivity. In general, solids are the best at transmitting electromagnetic waves, followed by liquids and then gases.
Electromagnetism is propagated by what waves?
Electromagnetism is propagated by electromagnetic waves, which consist of electric and magnetic fields oscillating together perpendicular to each other and to the direction of wave propagation.
What generates electromagnetic waves?
Electromagnetic waves are generated by the acceleration of charged particles, such as electrons, in an electric or magnetic field.
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.
What are sub atomic particles of energy and matter propagated by electromagnetic waves?
Subatomic particles of energy are photons, while subatomic particles of matter are electrons, protons, and neutrons. Electromagnetic waves propagate by the exchange of photons, which carry the electromagnetic force.
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.
Can rhythmic movement of air molecules produce electromagnetic waves?
No, the rhythmic movement of air molecules does not produce electromagnetic waves. Electromagnetic waves are generated by the oscillation of electric and magnetic fields and do not require a medium, such as air, to propagate.
Are vocal sounds mechanical or electromagnetic?
Vocal sounds are mechanical in nature. They are produced by the vibration of vocal cords in the larynx and then propagated through the air as sound waves. Electromagnetic waves, on the other hand, are a different type of wave that includes light and radio waves.
How do electromagnetic waves begin?
Electromagnetic waves are generated when electrically charged particles are accelerated. This acceleration creates changing electric and magnetic fields which propagate through space as electromagnetic waves. These waves can vary in frequency and wavelength, giving rise to a wide range of electromagnetic radiation, from radio waves to gamma rays.
How are elctromagnatic waves generated?
Electromagnetic waves are generated by accelerating electric charges. When an electric charge is accelerated, it creates a changing electric field which, in turn, generates a changing magnetic field. These changing electric and magnetic fields propagate through space as electromagnetic waves.
