In our daily lives, electromagnetic waves—commonly known as radio waves—are all around us, yet their presence often goes unnoticed because they are invisible to the naked eye. The Coursera course ‘生活中的電波’ (Electromagnetic Waves in Everyday Life) offers an engaging and comprehensive overview of how these waves are utilized in various applications, from cooking to communication and astronomy. This course is designed to help learners understand the fundamental principles behind electromagnetic waves and appreciate their significance without feeling overwhelmed or fearful.
The course is structured into several insightful modules. It begins with an explanation of microwave ovens, illustrating how they efficiently heat our food and what safety precautions we should observe. Next, it delves into broadcasting, revealing how radio signals transmit information globally, and explores the different frequency ranges involved. The course then examines modern wireless technologies such as cellular networks, Wi-Fi, and Bluetooth, explaining the underlying technologies that keep us connected.
Further, it introduces less familiar but equally fascinating topics like wireless power transfer, RFID systems, radar technology, GPS, radio astronomy, and addresses common safety concerns related to RF radiation. Throughout, the course uses accessible language and practical experiments to demystify complex concepts, making it suitable for learners of all backgrounds.
I highly recommend ‘生活中的電波’ for anyone interested in understanding the science behind the wireless world we live in. Whether you’re a student, a professional in technology, or simply curious about how electromagnetic waves shape our daily experiences, this course will deepen your understanding while igniting your curiosity. It’s a perfect way to see the invisible forces that influence and enhance our modern lives.
