electromagnetic waves are wave that do not require a material medium for their propagation while mechanical wave requires a material medium for example light wave is an electromagnetic wave it does not require any material medium(depends on air or water)for their propagation i.e even in the absence of air light will still travel... sound wave is a mechanical wave because sound do not travel in a vacuum....
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
No difference at all. Radio waves are one of many types of electromagnetic waves.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
Mechanical waves require a medium to travel, where electromagnetic waves do not.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
Mechanical waves travel fastest in mechanically-most-dense media. Electromagnetic waves travel fastest in optically-least-dense media.

mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
Electromagnetic waves can travel through space.Mechanical waves need matter to transfer energy.

maybe? ----- No, you are forgetting about electromagnetic radiation such as a light, radio, x-rays, and so on that also have wave properties. Mechanical waves are able to travel through matter but electromagnetic waves can travel in a vacuum.
Seismic waves are mechanical waves.
