What is light, and how can it travel in a vacuum forever in all
How can light (or electromagnetic radiation) travel through a vacuum when there is nothing there to act as a medium, and do so forever in all directions? For example the light coming from a star millions of light years away. Light is observed as traveling at velocity v=c, according to the second postulate of special relativity. But according to ...
Does Light Travel Forever?
In contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. This is why light from distant stars can travel through space for billions of light-years and still reach us on earth.
How fast does light travel?
The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c ...
How do we know that light can travel through a vacuum?
The first is by observation of the Sun and other stars. Astronauts have measured the pressure in outer space and found that there is a very good vacuum, much better in fact than that which we can easily make on earth. The second is through observations on earth. Scientists have measured the speed of light in a vacuum very carefully, and they ...
electromagnetic radiation
Light may seem to be an exception, leading many to say that light is a wave that can travel through a vacuum with no medium. Light doesn't use EM fields as its medium; light IS an EM (electromagnetic) wave. Maxwell's equations tell us that a magnetic field changing in time causes an electric field to change in space, and an electric field ...
How Does Light Travel?
Light actually "slows down" every time it has to travel through anything but a vacuum. Look up Cherenkov radiation to see what happens when light initially travels faster than it can through a ...
How does light travel?
And how can it behave like a wave and pass through a vacuum, when all other waves require a medium to propagate? ... So how does light travel? Basically, traveling at incredible speeds (299 792 ...
The Nature of Light
introduction. Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.
Understanding light and other forms of energy on the move
All light shares three properties. It can travel through a vacuum. It always moves at a constant speed, known as the speed of light, which is 300,000,000 meters (186,000 miles) per second in a vacuum. And the wavelength defines the type or color of light. Just to make things interesting, light also can behave as photons, or particles. When ...
Mechanical waves and light (article)
These are called mechanical waves . Sound waves, water waves, and seismic waves are all types of mechanical waves. Other waves, called electromagnetic waves can travel through a medium or through a vacuum where there is no matter, such as outer space. Light is a form of electromagnetic wave. The amplitude and frequency of both mechanical and ...
Light Waves
It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space.
Light: Electromagnetic waves, the electromagnetic spectrum and photons
Electromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation. While these forms of energy might seem quite different from one another ...
Anatomy of an Electromagnetic Wave
An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). An electron volt is the amount of kinetic energy needed to move an electron through one volt potential. Moving along the spectrum from long to short wavelengths, energy increases as the wavelength shortens.
Light basics
Light can travel through empty space. Unlike sound, which needs a medium (like air or water) to travel through, light can travel in the vacuum of space. Light travels in straight lines. Once light has been produced, it will keep travelling in a straight line until it hits something else.
The Nature of Light
Summary. Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.
23.2: Electromagnetic Waves and their Properties
c is the symbol used to represent the speed of light in a vacuum, and its value is 299,792,458 meters per second. When light travels through medium, its speed is hindered by the index of refraction of that medium. Its actual speed can be found with: \(v=\frac{c}{n}\). The Doppler effect is very commonly observed in action.
3.1: Light as a Wave
The wave equation included physical constants from both electricity and magnetism, and extracting the wave speed from this equation resulted in a number Maxwell was already familiar with - the speed of light. It is traditional to denote this speed with a lower-case 'c': c = 3.0 ×108m s (3.1.1) (3.1.1) c = 3.0 × 10 8 m s.
How Does Light Travel?
A Ray of Light. When an electromagnetic source generates light, the light travels outward as a series of concentric spheres spaced in accordance with the vibration of the source. Light always takes the shortest path between a source and destination. A line drawn from the source to the destination, perpendicular to the wave-fronts, is called a ray.
Turns out you can transmit sound in a vacuum, just not very far
Sound waves travel by vibrating through the particles of a medium, such as air or water, from a source to a receiver. So in a vacuum, there is no travel medium.

They always travel through the vacuum of space at 186,400 miles per second—the speed of light—which is faster than anything else. Too bad we can glimpse only about 0.0035 percent of the light ...
Can light travel in vacuum?
Of course yes. Light from sun reaches earth through the vacuum present in the space. Light does not require any medium to travel. However, Light can also travel in medium like air, water and solids. Example,we can see things inside water and glass which is a liquid and solid, which is due to travel of light. Suggest Corrections.
