Video Summary

Electromagnetic radiation is all around us, even though we can't see most of it. It's the foundation of our modern world, from radio waves to x-rays. Electromagnetic waves are produced by the vibration of charged particles and have electrical and magnetic properties. They travel through the vacuum of space at the speed of light. The electromagnetic spectrum is a range of frequencies that includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Different objects emit, reflect, and absorb electromagnetic radiation at different wavelengths. This allows scientists to study the composition and properties of objects by observing them at different wavelengths. The electromagnetic spectrum is a powerful tool that we use to learn more about our world and universe.
