Wavelength = (speed) divided by (frequency) = (300,000,000) / (60,000) = 5,000 meters
Alarm systems are (dis)armed (basically) by transmitting a code on a given frequency. It is insufficient to know the frequency alone.
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.
Wavelength = (speed) divided by (frequency) = (300,000,000) / (60,000) = 5,000 meters
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
Radio wave is not a longitudinal wave it is a transverse wave
radio wave + fireFire + radio wave = Laser
A radio
"Radio wave" is not like the others. "Radio wave" doesn't belong.
Infrared Wave
Radio Wave + Radio Wave = Radiation
The radio wave I believe.
