the very low frequencies up through the AM radio broadcast band.
Light is the visible form of electromagnetic waves.
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.

No. Electromagnetic waves are light waves that include gamma waves, x-rays, UV light, visible light, infrared light, microwaves, TV waves, and radio waves--basically any form of radiation.
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
