The portion of the electromagnetic spectrum between the frequencies of 10 KHz and 3 MHz.
an electromagnetic wave with a wavelength between 0.5 cm to 30,000 m
an oscillating wave in the radio frequency portion of the electromagnetic spectrum
_A wave for transmitting information in whiclthe medium is long wave electromagnetic energy (above ELFVLF region).
A combination of electric and magnetic fields varying at a radio frequency and traveling through space at the speed of light.
An electromagnetic wave of a frequency arbitrarily lower than 3000 GHz.
Using radio-frequency energy to heat the skin, the new Thermacool treatment causes underlying collagen to shrink and contract, resulting in a slight "mini lift".
a light wave that oscillates in the range from 1 million to 1 billion times per second. Radio waves are often used to send information that is received by radios and TVs. However, you can generate a radio wave (that won't have much useful information) by slowly peeling adhesive tape from a surface; do it near a transistor radio and you will hear snaps and pops.
A radio-frequency electronmagnetic wave.
Any electromagnetic wave at a frequency between approximately 10 kilohertz and 300,000 megahertz (a radio frequency range).
An electromagnetic wave with a frequency between 100 MHz and 3,000,000 MHz.
An electromagnetic wave of frequencies between approximately 20KHz and 3GHz.
Electromagnetic radiation with a frequency lying within a radio frequency band.
