The video explores the evolution and significance of radio, focusing on amplitude modulation (AM) and frequency modulation (FM). It explains how modulation works by attaching audio signals to carrier waves, allowing long-distance transmission. AM modifies the amplitude of the carrier wave, while FM alters its frequency. FM is preferred for music due to superior sound quality, despite its limited range compared to AM. AM is more cost-effective and covers larger areas, making it suitable for news broadcasts. The video concludes by highlighting radio's enduring role in communication.
