Wavelength and period are related through the speed of the wave, c, because speed is defined as space travelled per unit time: !=!! (1) The number of complete cycles –the number of times the wave repeats itself– in one second is called the frequency of the wave, ν. Thus, the frequency is the inverse of the period, and is
In this lesson, we will stretch the graph horizontally, changing the distance between peaks of the wave, called wavelength or period. We will find the period and frequency from the equation and also from the graph of a wave. We will graph waves, given the equation. 3.

14.To recap: The period, or wavelength is the x-distance between the tops of two consecutive waves. If you are given the graph, you can measure the period directly. The frequency is the reciprocal of the period. Frequency and period can be found from the equation using the formulas here.
J·s and the variable ν represents the frequency in 1/s, s-1, or Hz (Hertz). This equation allows the calculation of the energy of photons, given their frequency. If the wavelength is given, the energy can be determined by first using the light equation (c = νλ) to find the frequency, then using Planck’s equation to calculate energy. ν =
“electromagnetic spectrum,” explain the relationship between frequency and wavelength, define amplitude, and give the relationship between energy received and distance from the source.
