what is the difference between mechanical and electromagnetic waves quizlet?

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.

As a mechanical wave travels through a medium, it loses energy to the medium. ... Non-mechanical waves are waves that do not require a medium for the transfer of their energy to occur. Electromagnetic waves are the only type of non-mechanical waves. They can travel through the vacuum of space.

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.

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. ... Electromagnetic waves are created by the vibration of an electric charge.

They both represent electromagnetic waves. These are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. ... Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.

Propagation of an Electromagnetic Wave Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. 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.

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.

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.

Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.

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.

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 created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. ... The propagation of an electromagnetic wave through a material medium occurs at a net speed which is less than 3.00 x 108 m/s.
68945
Electromagnetic waves vary in wavelength and frequency. Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy. The speed of a wave is a product of its wavelength and frequency.

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. ... travel at the same speed through a vacuum or the air.

They are both waves, so yes. Electromagnetic waves are obviously waves made up of an electric field that is oscillating and a magnetic field that is oscillating. One unique characteristic it has is that it doesn't need a medium to travel in (it can travel through space). Sound on the other hand is a vibrational wave.

When EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. ... In a vacuum, EM waves transfer energy only by moving potential energy from one place to another. But when EM waves encounter matter, their energy can be converted into many different forms.

Most of the mathematics and properties of mechanical waves apply to light waves. Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave.
