Radio Waves

November 12, 2025Β  β€’Β  EPISODE 286

How do invisible waves travel across the world and beyond? In this episode of Science LIVE, Dr. Roger Billings dives into the fascinating science of radio wavesβ€”how they’re created, how they move through space, and how they make long-distance communication possible. From the basics of frequency and transmission to early breakthroughs like Morse code and modern applications such as HAM radio and space communication, join us as we explore the hidden currents that keep us connected.

    Do Truck drivers use ham radio and how would they have a radio tower.

    Morse code was used for world war one and two when their radio was broken.

    I did not know about the radio waves – am and fm. Is that why there is such a high sound when the am radio is not on the right Channel

    Did you know: The fictional astronaut Buzz Light-year from Disney Pixar’s Toy Story, is actually named after the second man on the moon, Neil Armstrong’s partner on Apollo 11, Buzz Aldrin.

    Fun fact of the day brought to you by a Disney nerd who fancies science, haha.

    why do you need a license for a ham radio?

    Reply
    • Camille

      You need a ham radio license because the Federal Communications Commission (FCC) requires it to ensure authorized use of radio frequencies, prevent interference with other services like cellular and GPS, and maintain order on the airwaves. The licensing process verifies that operators have the necessary knowledge of radio regulations and safe operating procedures before they transmit.

    How can Morse Code can be interpreted?

    Reply
    • Alexander

      Morse code is interpreted by translating a sequence of short and long signals (dots and dashes, or dits and dahs) into letters and words based on a standard alphabet chart. For audio transmission, the signals are heard as beeps, while visual transmission uses light flashes or physical movements. Key to interpretation is understanding the timing, where the spaces between dits/dahs, between letters, and between words have different durations.

    Is braille tied into morse code?

    Reply
    • Camille

      No, Braille and Morse code are not directly tied together; they are separate systems that both serve as codes for representing letters, but they are fundamentally different. Morse code uses a series of audible or visual signals (dots and dashes), while Braille uses a tactile system of raised dots. They do share the principle of assigning shorter codes to more frequent letters for efficiency.

    Reply
    • Camille

      No, Morse code is not a universal language, but it is a system that can be adapted for many languages, and International Morse Code is the most common version for Latin-alphabet languages. Adaptations are made by creating specific Morse code sequences for letters in different alphabets, such as Greek or Cyrillic. For languages with thousands of characters, like Chinese, a different approach is used where four-digit number codes represent each character, which are then transmitted using standard Morse code.
