Solid, then liquid, then gas.
In a vacuum.

According to the table the medium that sound travels at fastest speed is the electromagnetic waves.
Within the same medium, all electromagnetic waves travel at the same speed.
Mechanical waves need a medium to travel in
Mechanical waves travel fastest in mechanically-most-dense media. Electromagnetic waves travel fastest in optically-least-dense media.

Sound waves travel fastest through solids. *Generally, sound waves travel faster as the density of the transmission medium increases.
According to the table the medium that sound travels at fastest speed is the electromagnetic waves.
Within the same medium, all electromagnetic waves travel at the same speed.
Mechanical waves need a medium to travel in
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 .
Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.
Primary (P) waves are the fastest. Followed by secondary (S) waves, then surface waves. P waves
Mechanical waves travel fastest in mechanically-most-dense media. Electromagnetic waves travel fastest in optically-least-dense media.
Yes they are the fastest!
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
Sound waves travel the fastest through nonporous solids.
