Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa. As the wavelength of light increases the energy decreases. [Check Answer] The approximate speed of a wave train can be calculated from the average period of the waves in the train, using a simple formula: speed (in knots, which are nautical miles per hour) = 1.5 x period (in seconds). The number of complete wavelengths in a given unit of time is called frequency (f). Key Points The frequency's value stays the same. Given equal wavelengths, a wave with greater amplitude will release more energy when it falls back to sea level than a wave of lesser amplitude. The reverse is also true. Answer (1 of 4): As the wavelength of the light increase so photon energy is reduced. As the frequency decreases, the wavelength gets longer. The wavelength of a photon depends on the frequency of radiation of the electromagnetic wave and is given by the relationship wavelength = speed of light/frequency. The number of complete wavelengths in a given unit of time is called frequency (f). A high energy light will have a shorter wavelength than a low energy light.
