Waves disturb or perturb the medium and this propagates the wave.
Nothing (say a vacuum). The medium is what the sound travels 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.
Electromagnetic wave, namely, light as it travels through denser medium its speed decreases from its speed when it travels through air or vacuum.
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
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.

No. It travels as electromagnetic waves. Compression requires a medium that is compressed (and rarefied) but light travels through vacuum.
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
Radiation doesnt need a medium because it travels through space
A vacuum.
Light travels through a vacuum, and through the densest metals (though not usually very far). But then gamma radiation and radio waves are examples of light...
Sound waves travel through any medium with the exception of vacuum. The denser the medium, the faster the sound waves travel, because the waves can be farther apart..
