No, they are very dangerous
first of all electromagnetic waves are energy waves. and we call electromagnetic waves RADIATION.
In a vacuum, all electromagnetic waves have equal velocity.
All electromagnetic waves travel at the speed of light in a vacuum.
The Electromagnetic Spectrum.
They are all basically the same thing, electromagnetic radiation, but with different frequencies. All these waves are em waves which travel with the speed of light and it is the common b/w all the waves.
Radio waves are transverse electromagnetic waves.
I think you are confusing something. Sound waves, and electromagnetic waves, are two different types of waves.
In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
All electromagnetic waves travel at the same speed.
