Unlike waves in water, for example, light waves don't require a medium at all. They can (and do) travel through a complete vacuum, for example.
If you'd like to read about this, the wikipedia article on light, and also on 'The Aether' will be of interest.
Light waves belong to the category of electromagnetic waves, which are a type of transverse wave that do not need a medium to propagate.
Transverse waves have the medium moving perpendicular to the direction of the wave movement. Examples include light waves and electromagnetic waves.
A wave is the type of disturbance that transmits energy through a medium. Waves can be mechanical, like sound waves and seismic waves, or electromagnetic, like light and radio waves. Waves transfer energy by causing particles in the medium to oscillate back and forth.
Transverse waves have a medium that moves perpendicular to the direction of the wave propagation. This motion can be seen in water waves or electromagnetic waves, such as light.
Electromagnetic waves do not require a medium to propagate and can travel through the vacuum of space. Examples of electromagnetic waves include light, radio waves, and X-rays.

radio waves do not require a medium to travel,it can even travel through vaccum

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 .
Electromagnetic waves do not require a medium to propagate and can travel through the vacuum of space. Examples of electromagnetic waves include light, radio waves, and X-rays.
Electromagnetic waves do not require a medium to propagate. They can travel through a vacuum, such as the waves that make up light, radio waves, and X-rays.
longitudinal waves
Transverse waves cause the medium to vibrate perpendicular to the direction of the wave. Examples of transverse waves include light waves and electromagnetic waves.
Electromagnetic waves, such as light waves and radio waves, can be transmitted in a vacuum because they do not require a medium to travel through. These waves propagate through the vacuum of space and can travel long distances without the need for a medium.
