Light waves are part of the electromagnetic force. Maxwell's laws show that electricity produces magnetism and magnetism produces electricity. The two propulgate through space as oscillating waves at ninety degrees to each other; as the electric wave moves it generates the magnetic one, and vice versa. Thus, it doesn't need a medium; it perpetuates itself.
It helps that photons, the smallest quantum "packet" of light, can't decay because decay would imply time, and photons exist outside of Time. Or perhaps it is better to say Time doesn't move for photons. This is a consequence of Einstein's General Theory of Relativity, that demonstrates that time slows down as one approaches the speed of light. Since photons travel at the speed of light, time slows to zero.
What else can I help you with?
Do light waves required a medium?
They dont need it, but they can use it
What types of waves don't need a medium?
Electromagnetic waves, such as light and radio waves, do not require a medium to propagate because they are composed of oscillating electric and magnetic fields. They can travel through a vacuum, unlike mechanical waves which require a medium for propagation.
Waves that dont require a medium are called?
Light waves and 'radio' waves (i.e. infra red, UV, xray, etc.) At one time it was thought they did have a medium. A sort of 'gelatin' that went throughout the universe. The called 'the ether'. You see the term used a lot in radio magazines of the 1910s and 1920s.
How does the non-mechanical waves move through the space?
Non-mechanical waves(radio waves) which are sent into space are nothing but electromagnetic waves similar to light waves.Unlike sound waves or water ripples(waves) which require a medium to propagate in,electromagnetic waves are self-sustaining waves.We know that a moving charge causes a magnetic field and a moving magnetic field induces an electric field.Since an electromagnetic wave comprises of both electric waves and magnetic waves which are caused by each other,therefore they dont require a medium for propagation.
It is possible for an electromagnetic wave to travel through a vacuum?
yes, they can travel.
What are mediums for light waves?
Light is considered a self-propagating wave. So it does not need a medium, which is why it reaches the earth from the sun. The mediums which dont absorb the light (and therefore allow light to travel through it) depend on the wave length of light. For example a gamma ray (has a very short wavelength) can travel through metal and takes a block of lead to absorb it.
How does light waves travel?
i dont know so tell me i dont know so tell me
What happens to light waves during reflection?
The angle of incidence of a light ray = the angle of reflection. Also, when light is incident on a medium of higher density than the current medium (e.g. a glass mirror in air) then the wave undergoes a 180 degree phase shift. If the surface is rough and bumpy, then the rays are scattered about all over the place. I hope this answers your question, i dont know how detailed an answer you wanted.
How do surface waves differ form body waves?
Body waves: seismic waves that travel through the body of a medium Surface waves: seismic waves that travel along the surface of a medium and have a strong effect near the surface of the medium than it has in the interior
Two differences apart from speed between light waves and sound waves?
the seriosly obviose one- one is for light the othe is for sound, if you dont know which is which then you need some help.....
When waves hit you whch way do you move?
you dont move beause all waves are too light or they are all coming at different directions
What is the fundamental difference between electromagnetic waves and other waves?
The fundamental difference is that electromagnetic waves do not require a medium to propagate, unlike other waves like sound waves which do require a medium (such as air, water, or solid material). Electromagnetic waves can travel through a vacuum, whereas other waves cannot. Additionally, electromagnetic waves consist of varying electric and magnetic fields oscillating perpendicular to each other, whereas other waves do not exhibit this dual field behavior.
