AM (Amplitude Modulation): Varies the amplitude of the signal to transmit sound.
FM (Frequency Modulation): Varies the frequency of the signal and usually offers better sound quality and less interference.
A radio is a device that receives electromagnetic waves and converts them into sound. Radio stations transmit signals at specific frequencies, and the radio tuner selects and amplifies those signals for listening.
The most common types are AM/FM radios, shortwave radios, digital radios (DAB/DAB+), internet radios, and two-way radios (like walkie-talkies).
AM (Amplitude Modulation) varies the signal strength to transmit sound, while FM (Frequency Modulation) changes the frequency of the signal. FM generally has better sound quality but shorter range, while AM covers longer distances but with lower sound quality.
