As time passes, the amplitude of AM radio waves is intentionally changed in order to add information to the waves that can be read at a distance.
The process of adding information onto a bare radio wave is called "modulation". It means changing something on the wave ... either its amplitude, frequency, or phase, or actually turning it on and off ... according to a pattern that the transmitting person and the receiving person have worked out and agreed to, so that when the transmitting person makes changes to the wave, the receiving person can figure out what those changes mean.
Microwaves ARE radio waves, with frequencies above 3 GHz.
ultrasonic wave is sound frequency
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.

Void+electricity
Radio wave + radio wave will make radiation.
A radio wave is a kind of electromagnetic wave.
yes, electromagnetic wave is a radio wave
A radio
Radio Wave + Radio Wave = Radiation
The radio wave I believe.
Radio waves are electromagnetic radiation.
No, a radio wave is not an example of a mechanical wave. A mechanical wave requires a medium to travel through, such as water or air, while a radio wave can travel through a vacuum because it is an electromagnetic wave.
No, radio waves are transverse waves, meaning the oscillation of the wave is perpendicular to the direction of wave propagation. Longitudinal waves have oscillations parallel to the direction of wave motion.
