how do electromagnetic waves travel through vacuum?
152721
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. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).

Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. ... It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.

All electromagnetic waves travel at 300,000 km/s in the vacuum of space. ("Speed of light.") Nothing travels faster than the speed of light.

['Electromagnetic radiation can travel through empty space. Most other types of waves must travel through some sort of substance. ... ', 'The speed of light is always a constant. ... ', 'Wavelengths are measured between the distances of either crests or troughs.']

As we know electromagnetic waves are created by charges in motion or by magnetic field created by charged particles. And for the flow of field other charge carriers are required but vacuum does not contain any charged particles and how these waves are being carried forward after they have been produced from a source.

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.

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

electromagnetic waves are a type of mechanical waves, specifically a transverse wave. they transfer energy. electromagnetic waves dont need a medium to travel through but mechanical waves do.

Electromagnetic radiation travels in wave packets known as photons that consist of propagating electric and magnetic fields. These photons undergo absorption when they transfer energy to atoms within a substance they are striking instead of transmitting through or reflecting off of it.

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 electric and magnetic fields traveling through empty space with the speed of light c. ... The wavelength λ of this wave is given by λ = c/f. Electromagnetic waves transport energy through space. This energy can be delivered to charged particles a large distance away from the source.

For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium.

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

TRUE - A sound wave transports its energy by means of particle interaction. A sound wave cannot travel through a vacuum. This makes sound a mechanical wave. ... FALSE - Only electromagnetic waves can travel through a vacuum; mechanical waves such as sound waves require a particle-interaction to transport their energy.

Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.

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.)
