Through what medium does light travel?
Light travels through a vacuum, and through the densest metals (though not usually very far). But then gamma radiation and radio waves are examples of light...
What do light waves travel best through?
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
How fast do light travels in a second?
The SI metre is defined such that the speed of light in a vacuum is exactly 299,792,458 metres per second. This equates to 186,282.4 miles per second.The figure is 186,282 miles (299,793 kilometers) per second
Which mechanism of heat transfer can work in a vacuum?
Heat is a form of energy. Atoms of a certain material begin to tremble very fast when heated and pass this movement on to other atoms. So I think -not shure, heat/ energy can only be passed through material, and so it is not possible in a vacuum.
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
What happens when light passes through vacuum?
it travels at c (speed of light in a vacuum)
Does light make noise when it travels through a vacuum?
No, light does not make noise when it travels through a vacuum.
What happens to speed of light when travel through plastic?
When light travels through anything that is not a vacuum, it will usually slow down.
What happens to speed of light when they travel through a vacuum?
In a vacuum, light always travels at the same speed, about 300 000 kilometers per second.
What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
What materials can light travel through faster than it travels through air?
Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.
How can you know that light travels through a vacuum?
light travels from sun to earth through vaccum, so its easily understood
What does light travel faster through?
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
In what does light travel?
Light travels in a straight line through a vacuum or transparent materials.
Light travels through?
nothing, as in no molecules present
Does light travels slowest through space?
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
Why is it important to explain the speed of light together with the medium in which the light travels?
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
