How does light travel from space to earth?
When light travels through space from the sun, all of the frequencies of light travel in a straight line. When light hits the atmosphere, however, the photons begin to collide with gas molecules. Many of these scattered photons fly toward the Earth, making the sky appear to glow.
Why can light travel through space to from the sun to the Earth but sound Cannot?
In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium. Similarly, we can still see light emitted from the sun even though a vacuum stands between the sun and earth.
Why can light travel from the sun to the Earth even though space is a vacuum?
So electromagnetic waves have not need any medium to propagate. Electromagnetic waves as well as the bullets (photons), they can be stopped or slowed down (attenuated) by any object. Therefore the photons or electromagnetic waves in vacuum can traveling indefinitely as long as they do not interact with another object.
How can light pass through a vacuum?
Light is an electromagnetic wave that does not require a medium for transmission. This means they can behave as both particles and waves. Because of this light does not require a medium for propagation. They can travel through a vacuum.
How does the light travel?
Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; (3) after being reflected from a mirror.
How does light and sound travel through space?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
How does light work in space?
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. In this case, some light is absorbed and lost as heat, just like sound.
Can light travel through a space?
Like all forms of electromagnetic waves, light can travel through empty space, as well as through matter. Light can be absorbed. Absorbed light energy is converted into some other form, such as thermal or heat energy.
Does light travel through space and time?
In all reference frames that actually exist, light travels through space and time in a normal way just like any other object. According to Special Relativity, as a frame goes faster, it shortens more in the direction of motion, relative to the stationary observer.
How does light travel through space without a medium?
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.
What happens to light waves when they travel through vacuum?
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.
How does light travel through the universe?
Light just keeps going and going until it bumps into something. Then it can either be reflected or absorbed. Astronomers have detected some light that has been traveling for more that 12 billion years, close to the age of the universe. Light has some interesting properties. It comes in lumps called photons.
What are three ways to travel at the speed of light?
Three Ways to Travel at (Nearly) the Speed of Light. 1 1) Electromagnetic Fields. Most of the processes that accelerate particles to relativistic speeds work with electromagnetic fields — the same force 2 2) Magnetic Explosions. 3 3) Wave-Particle Interactions.
