Most forms of energy do NOT require a medium for transmission.
There are several types of energy:
1. Magnetic
2. Gravitational
3. Electromagnetic
4. Nuclear
Sound is the only one that requires a medium for transmission.
5. Sound
Sound travels by vibrating the Particles in the matter that it is traveling through.
Electric waves travel through a medium or a vacuum. The vacuum is a medium manifested by the free space resistance z = 375 Ohms. Z is realted to Planck's Constant h=zQ^2, where Q is the free space charge Q= 4/3 E-18 Coulombs.
Radiation is the fastest method of thermal energy transfer through a vacuum because it does not require a medium for propagation. Radiation can travel through a vacuum at the speed of light.
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
A medium is a material through which a wave travels. These can include solids, liquids, and gases. However, some waves, like light waves, can also travel through a vacuum.
Nothing (say a vacuum). The medium is what the sound travels through.
Waves disturb or perturb the medium and this propagates the wave.

The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.

The refractive index indicates how much light is slowed down as it travels through a medium compared to its speed in a vacuum. Since light travels more slowly in a medium than in a vacuum, the refractive index of the medium is always greater than 1.

nothing, as in no molecules present
A vacuum.
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
