Electromagnetic Spectrum
The longer the wavelength, the lower sounding frequency. The shorter the wavelength, the higher sounding frequency. This is because the shorter frequency waves have more energy than the longer frequency waves and energy can easily pass through shorter waves to get from one place to another.
