specific frequency that a radio station is assigned and uses to broadcast signals

an electric signal with only two possible values: ON and OFF

waves created by vibrating electric charges; consists of vibrating electric and magnetic fields, and can travel through a vacuum or through matter

electromagnetic wave with a wavelength less than about 100 trillionths of a meter; usually emitted from a decaying atomic nucleus

system of satellites and ground monitoring stations that enable a receiver to determine its location at or above Earth's surface

electromagnetic wave with a wavelength between about 1mm and 700 billionths of a meter

electromagnetic wave with a wavelength between about 0.1 mm and 30 cm

process of adding a signal to a carrier wave by altering the carrier wave's amplitude, frequency, or other property

massless energy-containing particle that electromagnetic wave sometimes behave like; the frequency of the electromagnetic wave increases with the energy of the particle

electromagnetic wave with a wavelength longer than about 10 cm, used for communication

device that transmits radio signals at one frequency and receives radio signals at a different frequency, allowing a user to talk and listen at the same time

electromagnetic wave with a wavelength between about 400 billionths and 10 billions of a meter

electromagnetic waves with wavelengths of 700 to 400 billionths of a meter that can be detected by human eyes

electromagnetic wave with a wavelength between about 10 billionths of a meter and 10 trillionths of a meter, often used for medical imaging
