What does it mean to be a high frequency wave?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength , while waves with a low frequency have a longer wavelength.

The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations . The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz.
