What is the medium for light travel?
We know that light doesn’t need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels. Light contrasts with sound, which travels through the air (or some other material medium).
Do electromagnetic waves require a medium?
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.
Why don t electromagnetic waves require a medium?
The electromagnetic waves are not mechanical waves. There are vibrations of electric vector and magnetic vector in them. These vibrations do not need any particles present in the medium for their propagation. That’s why electromagnetic waves do not require any medium for propagation.
What vibrates in light waves?
A light wave is an electromagnetic wave which travels through the vacuum of outer space. Light waves are produced by vibrating electric charges., An electromagnetic wave is a transverse wave which has both an electric and a magnetic component. Electromagnetic waves exist with an enormous range of frequencies.
Is there an ether?
ether, also spelled aether, also called luminiferous ether, in physics, a theoretical universal substance believed during the 19th century to act as the medium for transmission of electromagnetic waves (e.g., light and X-rays), much as sound waves are transmitted by elastic media such as air.
Does light travel in ethers?
No,it is a proven fact that light actually does not travel in any medium called ether.Before the advent of the relativity concept, it was believed that there was a medium called ether which surrounded us.But it meant that light would travel in ether at the c(3*10^8) and in other mediums it would travel at different speeds depending on the
Does light need a medium to travel through?
Ok, you are going to hear all about how light doesn’t need a medium to travel through. You can safely ignore this line of unreasoning. Maxwell’s equations require we calculate the permeability and permitivity of free space in our calculations. No other solutions to electromagnetic waves has been discovered. No other formulas are used.
Is there such a thing as an ether?
Almost every single physicist today will tell you that there is no such thing as an ether or aether that is required for light to travel through, and that it is as outmoded, obsolete idea. A lot of people will claim that the Michelson-Morely disproved the existence of an ether.
What is the difference between light and light waves?
Light can act as a set of Photons (a energy bundle) or set of quanta. On the other hand, light can also act as a wave. Now the big question arises that if light is a wave than light should also need a medium to travel between two frames. Even “vacuum” ha The answer to this question is really complex. But I will try to explain in easiest words.
