π Topic Summary
Wireless signals are all around us, carrying information without the need for wires! Think of it like sending messages with light: you can't see the light itself unless it bounces off something, but it's there, carrying the message. Wireless signals use radio waves to transmit data between devices like your phone, laptop, and the Wi-Fi router. This activity will help you understand how these signals work and how they travel through the air. Let's explore the invisible world of wireless communication!
