what is the difference between sound and electromagnetic waves?

2) Sound waves are elastic waves and propagate through actual vibrations of constituent particles in the medium it travels though. The EM waves on the other hand are due to oscillating electric and magnetic fields perpendicular mutually and also to the direction of motion.

What are the differences between sound waves and electromagnetic waves? Propogation: Sound waves are longitudinal, meaning that the vibrations occur parallel to the direction of propogation (travel). Electromagnetic waves are transverse, meaning that the vibrations occur perpendicular to the direction of propogation.

Electromagnetic waves are waves that contain an electric field and a magnetic field and carry energy. They travel at the speed of light.

As per the medium, the waves can be differentiated as mechanical and electromagnetic waves. 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.

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.)

An electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. ... A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.

Sound is a movement of air at any given wavelength. ... The average human being can only hear sounds between 20Hz-20kHz. Acoustics are the perception of sound passing around, in, or through a given medium(ex. air, room, guitar, water).

Electromagnetic waves can travel through water; mechanical waves can only travel through solid matter.

Electromagnetic Waves have different wavelengths. Wavelength is the distance between one wave crest to the next. Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.

'Electromagnetic radiation' is physically the same as 'electromagnetic waves'. Quantum mechanics show that the waves have a particle nature. To put it another way, the amplitude of electromagnetic waves are constrained by discrete values. However, they are still 'waves' in the most general sense.

Light and sound are not on the same spectrum. Light belongs to the electromagnetic spectrum but sound does not. ... Sound however, is a longitudinal wave - a wave that vibrates in the direction that it is travelling. Sound requires a medium to travel through whereas electromagnetic waves like visible light do not.

Mechanical vs Electromagnetic Waves Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air.

Waves are moving energy. Light waves are unique in their ability to travel through a vacuum (space). Sound is a form of energy that results when vibrating materials produce waves that move through matter.

Both are electromagnetic waves, quantized as photons. The only difference is the frequency of oscillation. Only wavelengths between 390 and 700 nm (approximately) are visible to humans. Radio waves are much longer (have much lower frequency).

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.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as 'electromagnetic' waves.

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.
