Radio waves are used not only in radio broadcasting but in wireless telegraphy, telephone transmission, television, radar, navigation systems and telecommunications. Unlike microwaves, radio waves are able to go over obstacles because of their longer wavelengths. radio waves of longer wave lengths are used for AM radio waves while radio waves of shooter wavelengths are used for TV and FM radio.
Large doses of radio waves causes cancer leukemia and other disorders.
