Light waves, unlike sound, do not require a medium.
Light waves do, but sound waves cannot, because in space is no medium to carry the vibration. Radio, TV and others can travel in space also.
Because of the force that it has, (kinetic)
space is a vacuum, and sound can't move through a vacuum.
slow down and refract
Light waves are electromagnetic waves that move at the speed of light. Sound waves are compression waves that move through a medium (air, liquids, solids), with varying speeds according to the medium.
No
sound waves can not travel through space since they use the air around us to move.
Yes, both light and sound can be described as waves. Light waves are electromagnetic waves, while sound waves are mechanical waves. They both propagate through a medium, although light can also travel through a vacuum.
The only waves that are known and proven to travel through empty space are electromagnetic waves. Theoretical gravitational waves also travel through empty space but have not yet been proven to exist. Both electromagnetic and gravitational waves move at the speed of light, thus it could be argued that a general term to describe all waves that can travel through empty space are waves that move at the speed of light.They say the message is the medium. In this case you could call it the "Ether". Ether is a blanket term describing information that is transmitted by any source through any medium. In this case the emptiness of space.
Scientist classify waves by moving through a medium and/or empty space. For example, a wall, air, water, space.
Energy in the form of electro magnetic waves. Some examples are light,heat,UV etc
actually light is nothing but combination of so many Waves. so we can say that light and waves are not different things that means if a light can move through a medium we an say that the waves an also move through that so medium refers the same meaning both in terms of light and waves
