Air.
No, apart from "spacetime". But it CAN travel through a medium such as air or glass.
No, radio waves do not need a medium to travel through. They are a type of electromagnetic wave that can travel through a vacuum, such as space. They can also travel through other mediums, such as air or water.
False. Waves do not carry the medium with them as they travel through it. Instead, they transfer energy through the medium without permanently displacing the particles of the medium.
Mechanical waves need a medium substance to travel through. Electromagnetic do not.
Electromagnetic waves can travel through space without a medium.
They travel through a material medium.
Sound waves are carried through a medium, such as air, water, or solid materials, to a person's ear. These waves travel through the medium by causing particles to vibrate, ultimately reaching the ear and allowing the person to perceive sound.
Sound waves travel through a medium such as air, water, or solid materials.
No.
Yes, transverse waves require a medium to travel through. Examples include water waves, which need water as a medium, and electromagnetic waves such as light, which can travel through a vacuum.
Light can travel through vacuum, but it is not a medium.
Any material through which any wave travels is called a medium. Ocean waves travel through the medium of seawater. Sound cannot travel through outer space, because there is no medium there to support sound waves. Mechanical waves such as sound and vibration require a medium through which to travel. Usually air, or a solid or liquid - matter in other words.
