Gamma rays Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Objects in space send out The energy equation is a direct relationship between frequency and energy because as frequency increases, so does energy. On the electromagnetic spectrum, this corresponds to the range of visible light, along with some overlap with the infrared and ultraviolet regions. Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths. If the energy of each wavelength is considered to be a discrete packet of energy, a high-frequency wave will deliver more of these packets per unit time than a low-frequency wave.
