1. Visible Light: This is the portion of the electromagnetic spectrum that our eyes can detect. It allows us to see the world around us. Different colors of light correspond to different wavelengths within the visible spectrum.
2. Radio Waves: These are used for communication, broadcasting, and radar. They have longer wavelengths than visible light and can travel long distances.
3. X-rays: These have very short wavelengths and are used in medical imaging and other applications. They can penetrate soft tissues, allowing doctors to see bones and other structures inside the body.
