Heat requires a medium. Sound requires a medium.
Because there's pretty much no physical matter in outer space, there's no heat or sound. Astronauts can experience heat after light energy converts to heat on their suits, and they can experience sound if they touch something (and the vibrations vibrate their ears as sound). Oh! And they get sound from radio waves (which are light!) that convert to sound.
Pure energy (like light, and gravity i guess) is the only thing that doesn't require a physical medium. I guess once an object is propelled through space, it continues moving without a medium too.
Fish need water to swim, monkeys need branches to swing, worms need dirt to wiggle forward.
That's the best answer i can give. Have a good day or something!

Which requires a physical medium in which to travel light or sound?
it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..
How sound waves differ from light waves?
Sound is a longitudinal wave and a light wave is a transverse wave. Sound requires a medium to travel through but light can propagate without any medium.
Does light travel in compression waves?
No. It travels as electromagnetic waves. Compression requires a medium that is compressed (and rarefied) but light travels through vacuum.
Can light be transmitted with or without a medium?
Light can travel with and without a medium.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.

How do sound and light travel?
The travelling of light and sound are two contrasting things.The sound wave being a longitudinal mechanical wave requires a medium and makes use of the inertia and elasticity of the medium in order to progress.Whereas a light wave being an electromagnetic wave requires no medium to travel and propogates by means of changing electric and magnetic fields.
Name one kind of wave that does not require a medium?
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.
Why does light travel faster that sound in the air?
Sound requires the physical motion of material. Light doesn't.
Why light travel in vacuum but not sound?
Light requires nothing more than a source for transmission. sound requires a source and a medium to conduct it. In vacuum, there is no conductor for sound.
How sound waves differ from light waves?
Sound is a longitudinal wave and a light wave is a transverse wave. Sound requires a medium to travel through but light can propagate without any medium.

Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
A wave that travels through a medium?
We know that a mechanical wave requires a medium through which to travel. The source puts the energy into the medium, and it propagates. A sound wave is a good example of this, and we can contrast it with an electromagnetic wave (like light). Light can travel through a vacuum; it doesn't require a medium for its propagation.
What type of wave requires no medium to travel through?
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
what vcan travel with or without a medium?
Light is a form of electromagnetic radiation that can travel through a vacuum, or a space with no air, meaning it does not require a medium to travel through. Other forms of electromagnetic radiation, like radio waves, microwaves, and x-rays, can also travel through a vacuum. Sound, on the other hand, is a form of mechanical wave which requires a medium to travel. This medium can be a solid, liquid, or gas, and is the way sound travels from one place to another. For example, when someone speaks, the sound waves travel through the air and reach our ears. In summary, light and other forms of electromagnetic radiation can travel with or without a medium, while sound requires a medium to travel.
