Radio Waves:These are a type of electromagnetic radiation with wavelengths longer than infrared light. They have the lowest frequency and longest wavelength of any wave in the electromagnetic spectrum. They're like the big semi-trucks on our highway analogy - slower and bigger than microwaves.
Infrared Waves: These waves sit between microwaves and visible light in the electromagnetic spectrum. They're like smaller delivery vans - faster than semis but slower than our microwave "trucks".
Electromagnetic Spectrum:This is a classification system for all types of waves, including radio waves, microwaves, infrared waves, visible light, ultraviolet light, X-rays, and gamma rays. It's like our road map showing where each vehicle (wave) belongs.
