Because they don't need any material substance to travel through

in order to get from place to place.

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.


Do light waves required a medium?

They dont need it, but they can use it


How does light waves travel?

i dont know so tell me i dont know so tell me


Is a microwave a mechanical wave?

No. Microwave is a radio wave, which is an electromagnetic wave.No, its actually an electromagnetic waves, just like X-rays and visible light...electromagnetic waves dont need to go through medium ( solid, liquid, gas).


How are mechanical waves made?

i dont know realy just fail it im telling you the truth even though you dont want to know the truth sorry if its like 1 question you dont get out of 20 then whatever no porb sorry ily jk i dont know u lmao :) Somebody else wrote that, and WHOEVER it was, obviously shouldn't have ANSWERED it. Just a tip: If you see a question, and you DON'T know the answer, wait for someone else to answer it so you don't look like an idiot on the internet. Now, on to the question at hand. Mechanical waves always require a medium, which are the actual material (or matter) that the wave travels through. Mechanical waves are made when particles of matter vibrate back and forth. Examples of Mechanical waves are ocean waves, sound waves, or even when you're in a stadium and and everyone moves their arms to make a theoretical "wave." Waves themselves are actually just a disturbance that transmits energy from place. There are two types of waves, Mechanical, and Electromagnetic. (FYI electromagnetic waves do NOT require a medium) I also know a whole lot about the anatomy of a wave, but I'll just wait for someone else to ask that question...


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.


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


If transverse waves dont move how do transverse waves transfer light from one place to another?

Of course it moves. The whole idea of a "wave" is that it moves.


What kind of wave are electromagnetic waves?

radio waves


Do hippos classify there eggs?

hippos dont have eggs


How do electromagnetic waves and light years relate?

Electromagnetic waves travel at the speed of light. Therefore, when we talk about distances in space, such as the distance between stars or galaxies, we often use light years as a unit of measurement. A light year is the distance that light travels in one year, which is approximately 9.46 trillion kilometers.
