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. The relationship between energy (E), frequency and wavelength can be described with this equation: The energy is simply the photons frequency multiplied by the Planck constant (h). Wavelength is related to energy and frequency by E = h = hc/, where E = energy, h = Plancks constant, = frequency, c = the speed of light, and = wavelength. It is measured in terms of Hertz (Hz) or s-1. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa. Lets consider a thread that is tied to an end. E) none of the above. b. The width of central maxima is given as-w = 2 a. The number of complete wavelengths in a given unit of time is called frequency (f). Therefore, as the wavelength of a wave increased, its frequency decreased.
