Sound requires a physical medium, such as air, water, or solids, in order to travel because it propagates through vibrations of particles in the medium. On the other hand, light does not require a physical medium and can travel through empty space as electromagnetic waves.

Which requires a physical medium in which to travel light sound or both?
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!
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.
Can you see light in a vacuum?
No, light cannot be seen in a vacuum because light requires a medium to travel through in order to be visible. In a vacuum, there is no medium for the light to interact with, so it cannot be seen.
Which wave requires medium?
Mechanical waves, such as sound waves and water waves, require a medium (substance) to travel through. Electromagnetic waves, like light waves, do not require a medium and can travel through a vacuum.
All waves need a medium to travel?
This statement is not accurate. Electromagnetic waves, such as light and radio waves, can travel through a vacuum where there is no medium. They do not require a physical medium like air or water to propagate.

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.
Can you see light in a vacuum?
No, light cannot be seen in a vacuum because light requires a medium to travel through in order to be visible. In a vacuum, there is no medium for the light to interact with, so it cannot be seen.
Which wave requires medium?

Which wave requires a medium for transmission light radio infrared or sound?
Sound waves require a medium, such as air, water, or solids, for transmission. Light, radio, and infrared waves can travel through a vacuum and do not require a medium for transmission.
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 .
Who can we say light does not need to travel in medium?
Light can travel in a vacuum without the need for a medium. This is because light is composed of photons which do not require a medium, unlike other types of waves such as sound waves that do need a medium to propagate.
