Radio Waves and Satellite Communication

Elaine, an educator at the California Science Center, introduces the museum and its space exhibits, including replicas of satellites and telescopes like Cassini, Hubble, and James Webb. She explains the history of satellites, the missions of these telescopes, and how they communicate with Earth using radio waves. The video includes an activity to explore radio wave transmission and interference, encouraging viewers to experiment with different materials. The video concludes with an invitation to visit the museum's website for more educational content.
