A medium :)
Mechanical waves require media through which they can travel.
Mechanical waves require a medium (substance) to travel in, other waves do not. For example, sound is a mechanical wave and require a medium (air, water, etc.), light is not a mechanical wave and does not require a medium
Electromagnetic waves, such as light waves and radio waves, do not require a medium to travel through. These waves can travel through a vacuum, unlike mechanical waves which require a medium to propagate, like sound waves in air or water waves in the ocean.
Not all waves require mediums to propagate.Sound waves can travel through solid, liquid and gaseous mediums, while, electromagnetic waves do not require any medium to travel through.
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
False. Electromagnetic waves do not require a medium to travel; they can propagate through a vacuum.
Mechanical waves are waves that require a medium in which to travel, i.e., a solid or fluid. As sound needs a medium to travel, sound is a mechanical wave.
Sound waves require a medium to travel through, and, since space is a vacuum, sound waves can't travel in it.
NO some waves like sound require matter to travel whereas light waves can travel in vacuum.
Electromagnetic waves, gravity waves.
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 .
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.
