Electromagnetic waves.
Light does travel through a vacuum.
No. Only light waves can travel through a vacuum.
i think voice cannot travel through vacuum.
Yes, any electromagnetic wave can travel through a vacuum.
No, compressional waves require a medium to travel through, so they cannot travel through a vacuum where there is no matter. Sound waves, which are compressional waves, cannot propagate through a vacuum.
Sound cannot travel through a vacuum as it needs a medium, such as air, water, or solid material, to propagate. In a vacuum, there are no particles for sound waves to travel through, so the speed of sound is essentially zero.
Yeah, radiation can travel in vacuum and a practical example of it is the radiation of sun coming to earth and traveling through space.
sound can't travel through a vacuum. or a place without air.
The vacuum becomes no longer a vacuum.
No, ultrasound cannot travel through a vacuum because it requires a medium, such as air or water, to propagate. In a vacuum, there are no particles for the sound wave to travel through, so it cannot propagate.
Sound.
Light can travel through vacuum, but it is not a medium.
