well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another
An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.
A deshawn wave!
E.M. waves require no medium. Sound waves require a medium.
Electromagnetic
It is electromagnetic radiation that needs no medium to travel in. Gamma rays, light and radio waves, all forms of electromagnetic radiation, can travel through the vacuum of space very well. In fact, they prefer it.
Sound requires a medium through which it can travel, such as air, water, or solid materials. When an object vibrates, it causes the particles in the medium to vibrate, creating sound waves that travel through the medium. The speed of sound in a medium depends on its properties, such as density and elasticity.
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.
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.
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
Mechanical waves need a medium substance to travel through. Electromagnetic do not.
Electromagnetic waves can travel through space without a medium.
Radio waves are a type of electromagnetic wave that do not require a medium to travel through, allowing them to propagate through the vacuum of space. In contrast, sound waves are mechanical waves that require a medium, such as air or water, to transfer energy and vibrations. Space is a vacuum, lacking the necessary medium, which is why sound waves cannot travel through it.
They travel through a material medium.
No, gravity is not necessary to hear sound. Sound can travel through different mediums, such as air or water, regardless of the presence of gravity. Gravity affects how sound waves travel through a medium but is not a requirement for sound to be heard.
The speed at which a wave travels through a medium depends on the properties of the medium. In general, the denser the medium, the faster the wave will travel. The speed of a wave can also be influenced by factors like temperature, pressure, and elasticity of the medium.
