- The electromagnetic spectrum. (Credit). 1  Electromagnetic waves carry transverse vibrations in electrical and magnetic fields, not vibrating particles.  Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum).

- The speed of electromagnetic radiation in a vacuum is 299,792,458 m/s. This is approximately three hundred million metres per second-nearly nine hundred thousand times faster than sound, which is why you see a flash of lightning before you hear the thunder.

- SECTION 3 Light 425 Waves in Empty Space On a clear night you might see the Moon shining brightly,as in Figure 16. Like other waves, light waves can travelthrough matter, but light waves are different from waterwaves and sound waves. Light from the Moon has traveledthrough space that contains almost no matter. You can seelight from the moon, distant stars, and galaxies because light isan electromagnetic wave.

Physics for Kids 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. The different types of waves have different uses and functions in our everyday lives.

How do electromagnetic waves travel through a vacuum? These changing fields form electromagnetic 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.

- 2 Answers. , over 40 years of teaching introductory physics. In free space they travel in the same way than any other electromagnetic waves such as light, infrared and ultraviolet waves do. Having larger wavelengths than these other electromagnetic waves, they can diffract more around obstacles: Radio propagation .

Difference Between Mechanical and Electromagnetic Waves Electromagnetic waves travel in a vacuum whereas mechanical waves do not. The mechanical waves need a medium like water, air, or anything for it to travel. The ripples made in a pool of water after a stone is thrown in the middle are an example of mechanical waves.

Propagation of an Electromagnetic Wave While the electromagnetic wave will travel at a speed of c (3 x 108 m/s) through the vacuum of interatomic space, the absorption and reemission process causes the net speed of the electromagnetic wave to be less than c. This is observed in the animation below.

- However, we do have some ideas about why light is able to travel through both vacuums and air with no problem. It all has to do with the dual nature of light. Thanks to Einstein and Bose we know that light is both a wave we know as electromagnetic radiation and a particle called a photon. The photon because of its weird nature as a force carrier called a boson has no mass. However it can still be absorbed, reflected, or refracted if it come in contact with a medium. That is why like sound the speed of light slightly varies between when it is in our atmosphere and when it is in space. When in the medium of air how it travel makes sense as waves travel by vibrating through a medium. In space the particle does not need to interact with a medium in fact its speed improves in a vacuum. The main thing that can stop or slow down light in space is gravity.

Communications System More about radio waves and electromagnetic radiation. Electromagnetic radiation (which includes radio waves, light, cosmic rays, etc.) moves through empty space at the speed of 299,792 km per second. Sunshine is a familiar example of electromagnetic radiation that is naturally emitted by the Sun. Starlight is the same thing from Suns that are much farther away.

Propagation of an Electromagnetic Wave 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). 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. This is depicted in the animation below. The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material.

- This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.) Nothing travels faster than light energy. It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.

- Report Abuse. 1  most of waves could travel through empty space. ex: 1. light waves. 2  All waves of the electromagnetic spectrum can travel through the vacuum of space at 3x10^8 m/s as they are transverse waves. sound waves - longitudinal waves cannot. 3  if there is empty space then only electromagnetic wave can travel through that.

Difference Between Light and Radio Waves The energy of the wave is in the electric and the magnetic fields and, therefore, the electromagnetic waves require no medium for propagation. In a vacuum, electromagnetic waves travel at the speed of light, which is a constant (2.9979 x 10 8 ms -1). The intensity/strength of the electric field and the magnetic field has a constant ratio, and they oscillate in phase. (i.e. the peaks and the troughs are occurring at the same time during propagation).

At what speed is the universe expanding? Is it faster or slower than the speed of light? 1 Electromagnetic radiation can be thought of as particles, called photons, that carry energy in straight-line paths through space. 2  As they move through space, photons carry electric and magnetic fields that oscillate at a certain frequency.

How do electromagnetic waves travel through a vacuum? In the simplest form electromagnetic waves travel like bullets through empty space. A bullet doesn't need a supporting medium to travel. Shoot and off it goes. What makes it more complicated is that EM particles, photons, are not exactly like bullets.

Properties of Light There are some general properties shared by all forms of electromagnetic radiation: It can travel through empty space. Other types of waves need some sort of medium to move through: water waves need liquid water and sound waves need some gas, liquid, or solid material to be heard.

Electromagnetic radiation Electromagnetic waves in free space must be solutions of Maxwell's electromagnetic wave equation. Two main classes of solutions are known, namely plane waves and spherical waves. The plane waves may be viewed as the limiting case of spherical waves at a very large (ideally infinite) distance from the source.

- Mobile phones and other wireless devices send information across free space using electro­. magnetic waves. To send these electromagnetic waves across long distances in free space, the frequency of the transmitted signal must be quite high compared to the frequency of. the information signal.

- Yes and No...electromagnetic waves travel at different speeds in different mediums, however in a vacuum all electromagnetic waves travel at c (3*10^8 m/s) or 186,000 miles per … second i believe :P. Scientists created a scalar called the index of refraction for materials that refract light such as glass and water.
