how are electromagnetic and mechanical waves alike?

Mechanical waves are caused by wave amplitude and not by frequency. Electromagnetic Waves are produced by vibration of the charged particles. 4. While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

"Electromagnetic field" just refers to the field created by static (electric field) or moving (magnetic field) charges. An electromagnetic wave is a certain configuration of the electromagnetic field. ... On a more formal level, an EM wave is any EM field that obeys the differential equations governing waves.

Electromagnetic Waves are produced by vibration of the charged particles. 4. While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance. Electromagnetic waves travel in a vacuum whereas mechanical waves do not.

Electromagnetic waves are transverse waves. Their vibrations, or oscillations , are changes in electrical and magnetic fields at right angles to the direction of wave travel. All electromagnetic waves: transfer energy as radiation from the source of the waves to an absorber.

Mechanical waves need matter to transfer energy, while electromagnetic waves do not, they can travel through space or a vacuum. Electromagnetic waves include the electromagnetic spectrum (This includes visible light, radio waves, gamma rays, x-rays, ultraviolet rays, infra-red waves, and microwaves.)

Electromagnetic waves are transverse waves with a wide range of properties and uses. Sound waves are longitudinal waves.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
106953
Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. ... While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

Types of Electromagnetic Waves. Electromagnetic waves are a form of energy waves that have both an electric and magnetic field. Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum. Electromagnetic waves are classified according to their frequency.
811628
Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. ... Sound waves require a material medium to travel, and hence, cannot travel in vacuum. The speed of light in a medium is constant.

What are electromagnetic waves? Electromagnetic waves are non elastic waves in the sense that they don't really need a material medium for their propagation like sound waves do.
295502
Electromagnetic waves do not require a medium and mechanical waves do require a medium to travel. ... Electromagnetic waves are always transversal, while mechanical waves can be transverse, longitudinal, or torsional.
701726
Electromagnetic waves do not require a medium in order to transport their energy. Mechanical waves are waves that require a medium in order to transport their energy from one location to another. ... Sound is a mechanical wave and cannot travel through a vacuum.

Propagation of an Electromagnetic Wave Electromagnetic waves are waves which can travel through the vacuum of outer space. ... Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.
