Oscillating electric charges.
They all are electromagnetic waves
Three examples of electromagnetic energy are visible light, radio waves, and X-rays.
At the speed of light - about 300,000 km/sec (3 x 108 m/sec)
No.
Yes.
The Moon are you a Idiot
All communication systems use electromagentic waves which by the law of Superposition of Waves travel independently in any meadium and hence do not interfere but if the frequencies tend to match then the carrier waves with amplitude modulation are more affected and give poor quality sound at the receiving end than the frequency modulated carrier waves.
when large waves join
wind is one of the main cause of waves
Sound Waves
waves
That varies, depending on the type of waves - e.g., water waves, sound waves, electromagnetic waves, etc.
