The amplitude of a wave determines its energy. The larger the amplitude, the more energy the wave carries.

Amplitude times frequency.
The amplitude of a wave is the factor that determines a wave's energy. Amplitude is the measure of the height of the wave, which correlates with the energy the wave carries. Waves with larger amplitudes have more energy.
The frequency of electromagnetic waves varies, which is determined by the energy of the wave. Higher energy waves have higher frequencies and shorter wavelengths, while lower energy waves have lower frequencies and longer wavelengths.
The amplitude of a transverse wave determines the amount of energy at one time. A higher amplitude corresponds to a greater amount of energy being carried by the wave.
The energy of a longitudinal wave is related to its amplitude, frequency, and wavelength, rather than its direction of oscillation. Longitudinal waves can have high energy if they have a large amplitude and high frequency, but the presence of longitudinal motion alone does not determine the energy of the wave.
