Sometimes, law enforcement agencies try to disrupt certain radio signals by a process known as jamming. Jamming a radio signal prevents it from being received by its intended recipients as an intelligible message. In order to jam a radio message, a radio signal with the same frequency as the targeted signal is transmitted into the air. If the jamming works, the original radio wave will have its amplitude affected by its interaction with the jamming signal. A successful jamming signal will reduce the signal-to-noise ratio of the targeted signal to the point where the information it carries cannot be understood. Which wave property is used to jam radio signals?
diffraction
absorption
interference
resonance
