No. We get electromagnetic waves from the sun. We can see stars and sun even though there is a virtual vacuum between us. Electromagnetic radiation or electromagnetic waves includes the radio and television signals that we can get from space satellites.
Sound is not an electromagnetic wave, it needs a medium.
What else can I help you with?
How mechanical and electromagnetic wave are different?
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
What do electromagnetic waves not need?
A fluid or medium.
What waves need a medium and which don't?
Mechanical waves, such as sound waves and ocean waves, require a medium (solid, liquid, or gas) to propagate. Electromagnetic waves, including light waves and radio waves, do not require a medium and can travel through a vacuum.
What waves can transfer energy with out a medium?
Electromagnetic waves, such as light and radio waves, can transfer energy through a vacuum without the need for a medium. This is because electromagnetic waves are made up of oscillating electric and magnetic fields that can propagate through empty space.
Can electromagnetic waves travel without a medium?
Yes, electromagnetic waves can travel through vacuum because they are self-propagating and do not require a medium for transmission. This is one of the unique properties of electromagnetic waves compared to other types of waves like sound waves.
How are em waves different from mechanical waves?
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
What medium is needed for electromagnetic waves?
Electromagnetic waves can travel through a vacuum, which means they do not need a medium to propagate. This is a unique feature of electromagnetic radiation compared to mechanical waves like sound waves which require a medium, such as air or water, to travel through.
What kind of energy does not need medium to travel?
electromagnetic waves
Why radiation waves does not need any medium?
they do. As you might be aware of, light( radiation wave) is made of electromagnetic wave and its medium is electromagnetic field. So basically the medium of radiation waves is electromagnetic field.
Do all waves need a medium?
No, not all waves require a medium to travel through. Electromagnetic waves, such as light, can travel through a vacuum because they are composed of oscillating electric and magnetic fields rather than requiring a physical medium.
What type of vibration does not need a medium through which to travel?
Electromagnetic waves.
What do electromagnetic waves need to travel?
Electromagnetic waves don't need anything to travel. This kind of waves does not need a medium to move through, therefore they can even travel through outer space.
