If the frequency of a wave increases, its energy will increase. High frequency light has short wavelengths and high energy. Energy is directly proportional to frequency and frequency is inversely proportional to the wavelength of the radiation. As the frequency decreases, the wavelength gets longer. b. In this figure, the amount of . Well, frequency is the same thing as pitch, and is measured in hertz (Hz). Patterns 5 and 6 have the same wavelength and frequency but the amplitude is different. Gamma rays Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. c) I, II, and IV What is the relationship between energy and frequency? 1 joule = 1 kg m2/s2 10. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. The amount of energy is directly proportional to the photons electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. Frequency has the units of cycles/sec or waves/sec, but scientists usually just use units of 1/sec or Hertz (Hz).
