📖 The Same Wave, Different Energies

Here's something mind-bending: the light you see, the WiFi carrying your messages, the X-rays seeing your bones, and the microwaves heating your food are ALL the same thing — electromagnetic waves! They only differ in wavelength and frequency. Radio waves can be kilometres long; gamma rays are smaller than atoms. All travel at 300,000,000 m/s through space. The whole spectrum is just one continuous family of energy-carrying waves!
