Electromagnetic Spectrum Explained
Electromagnetic waves are amazing because they can travel through both empty space and solid objects. These waves consist of electric and magnetic fields working together to carry radiant energy. They all move at the incredible speed of light—about 300,000,000 meters per second!
The electromagnetic spectrum organizes these waves based on their frequency and wavelength. From longest to shortest wavelength, the spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet (UV), X-rays, and gamma rays. Each type serves different purposes in our daily lives.
Radio waves broadcast our favorite shows and music, while microwaves help cook our food and transmit phone signals. Infrared waves deliver heat from the sun and heaters, and visible light allows us to see the world around us. The shorter wavelengths include UV rays (which cause sunburns), X-rays (used to see inside our bodies), and gamma rays (powerful enough to destroy cancer cells).
Did you know? The electromagnetic waves you use every day—from checking your phone to microwaving popcorn to seeing this text—are all fundamentally the same type of energy, just with different wavelengths and frequencies!

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
