What is the difference between frequency and energy

S is called Planck's constant. Since the energy goes up as the frequency increases, the energy is directly proportional to the frequency. Because frequency and wavelength are related by a constant (c) the energy can also be written in terms of wavelength: E = h ... That is, energy in inversely proportional to wavelength.

The greater the energy, the larger the frequency and the shorter (smaller) the wavelength. Given the relationship between wavelength and frequency - the higher the frequency, the shorter the wavelength - it follows that short wavelengths are more energetic than long wavelengths.
