	You can look at the propagation of the light as electric field and magnetic field propagating perpendicular to each other. You can also consider the propagation of the wave in space or propagation in time. The distance between two crests is the wavelength~~, and~~ the ~~modulation~~ of the ~~field~~ the ~~time between two crests~~ is the ~~period~~.		You can look at the propagation of the light as electric field and magnetic field propagating perpendicular to each other. You can also consider the propagation of the wave in space or propagation in time. The distance between two crests or troughs is the wavelength. Frequency is the number of occurrences of a repeating event per unit time.The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.

	Much of the science of photonics requires a deep understanding of how light propagates through space and through various materials. It is useful to memorize the symbols that are consistently used for properties such as frequency and wavelength. At the same time be aware that different disciplines may have different names or variables used for the same phenomenon. In addition the same greek letter may be used to refer to different quantitites depending on the context. Refer to the [[Acronyms_and_Unit_Abbreviations#Variables_and_Constants \| Variables and Constants Wiki Page]] if you get confused.
