THE ELECTROMAGNETIC SPECTRUM
10
RADIO WAVES : have a very wide range of wavelengths
SPECTRUM : The electromagnetic __________ is a continuum of electromagnetic waves arranged according to frequency and wavelength.
MICROWAVES : have smaller wavelengths than radio waves
RADAR : short for radio detecting and ranging
LOW FREQUENCY : ___ ______ waves are suitable for communication over great distances.
CELLPHONE : radio transmitter and receiver that uses microwaves
FREQUENCY : number of cycles a wave completes in one second; expressed in Hertz
RADIO TRANSMITTER : attaches information to the radio signal by modulating it
WAVELENGTH : the distance between successive crests of a wave
VIOLET : color of the lowest wavelength
