4. Infrared: The Superhero of Waves

With great power comes great responsibility, but with infrared waves, you get the power to see through materials like a superhero, and control your TV like a couch-crime-fighter: Infrared waves are electromagnetic radiation with longer wavelengths than visible light, and they have the power to penetrate certain substances; used in thermal imaging cameras to find heat signatures and in remote controls to transmit signals, they are not quite superhero-level with their limited range and weakness against obstacles like walls and sunlight.

9. Infrared Waves: The North Star of Rescues

Infrared waves: not just for super-spies and paranoid homeowners anymore! In fact, they're quite the heroes in search and rescue missions, assisting firefighters in dousing wildfires and guiding rescue teams through low-visibility conditions like it's the North Star of advanced imaging technology: by detecting heat signatures through thermal cameras, infrared technology identifies the potentially explosive hot spots in raging flames, as well as pinpoints the locations of missing people or vessels, making rescues genuinely hotter than ever.
