how is electromagnetic waves different from mechanical?
54212
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.

Sound you hear, light you see. Sound is a mechanical wave whereas light is an electromagnetic one. ... Light does not need a medium to travel to, sound does. They are both waves but only light is also a particle.

Water waves and sound waves are examples of mechanical waves. Light waves are not considered mechanical waves because they don't involve the motion of matter. ... Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave.

A mechanical wave is one that needs a medium through which to travel. ... An electromagnetic wave does not require a medium to travel. All electromagnetic waves are transverse.

Mechanical waves are mostly longitudinal waves. It means the constituents of the naterial through which the wave is moving are oscillating in the same direction as the wave itself. ... Also unlike a mechanical wave, an electromagnetic wave does not require a medium to travel. It can travel in completely empty space.

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 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.

Electromagnetic (EM) 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.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. ... They are deflected neither by the electric field, nor by the magnetic field.

"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.

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.)

Rather, we are talking about the waves that transmit radio signals. The main difference between radio waves and sound waves is that radio waves are a type of electromagnetic wave that can travel when there is no medium, whereas sound waves are a type of mechanical wave that cannot travel if there is no medium.
1058264
Common types of mechanical waves include sound or acoustic waves, ocean waves, and earthquake or seismic waves. ... The transmission of electromagnetic waves does not require a medium and electromagnetic waves are able to travel through vacuums.

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.

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. ... While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

Properties of electromagnetic waves An electromagnetic wave is perfectly happy to do that. An electromagnetic wave, although it carries no mass, does carry energy. It also has momentum, and can exert pressure (known as radiation pressure).

Propagation of an Electromagnetic Wave 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.
