4.3 Light and the Electromagnetic Spectrum

The electromagnetic waves that we can detect with our eyes are a small portion of the entire electromagnetic spectrum. However, there are some devices that have been developed to detect other frequencies. Like the atenna of a radio, it can detect radio waves. We can't see radio waves. Radio waves and infrared waves have longer wavelengths and are lower frequency than visible light.
