Wavelength

Wavelength
In physics wavelength is the distance between repeating units of a propagating wave of a given frequency. It is commonly designated by the Greek letter lambda (λ). Examples of wave-like phenomena are light, water waves, and sound waves. The wavelength is related to the frequency by the formula: wavelength = wave speed / frequency. Wavelength is therefore inversely proportional to frequency. Higher frequencies have shorter wavelengths. Lower frequencies have longer wavelengths, assuming the speed of the wave is the same.
在物理波长的距离是一个波传播的一个给定频率的重复单元之间的。它是由希腊字母λ通常指定（λ）。波现象的光，水波和声波的例子。波的频率相关公式：波长=波速/频率。因此，波长与频率成反比。高频率的波长短。较低的频率的波长较长，假设波的速度是相同的

基本简介

Wavelength of a sine wave.
In a wave, properties vary with position. For example, in a sound wave the air pressure oscillates, while in light and other electromagnetic radiation the strength of the electric and the magnetic field vary.
