More Information
Radio waves have the longest wavelengths in the electromagnetic spectrum and the lowest frequencies. They can range in length from a few millimeters to thousands of kilometers.
Tips
A common mistake is confusing wavelength with frequency. Wavelength is the distance between successive crests of a wave, while frequency is how often those crests pass a point in a given time period.
