As a domain expert in physics, I can explain the concepts of amplitude and frequency in the context of wave phenomena. Amplitude is a measure of the maximum displacement or distance moved by a point on a wave from its equilibrium position. In simpler terms, it's the highest point that the wave reaches as it travels through its medium. For example, in a water wave, the amplitude might be the highest point above the water's surface that the wave crest reaches. Frequency, on the other hand, is the number of complete wave cycles that pass a given point in a certain period of time. It is often measured in Hertz (Hz), which is equivalent to cycles per second. A higher frequency means that more wave cycles are occurring in the same amount of time. Now, let's translate that into Chinese: 作为一名物理学领域的专家，我可以解释波动现象中的振幅和频率的概念。 振幅 是衡量波上任意一点从其平衡位置达到的最大位移或移动距离的量度。更简单地说，它就是波在传播过程中达到的最高点。例如，在水波中，振幅可能是波峰达到的最高点，超出水面的高度。 频率 则是在一定时间内通过某一给定点的完整波动周期的数量。频率通常以赫兹（Hz）为单位，即每秒周期数。频率越高，意味着在相同的时间内发生的波动周期越多。 read more >>

A wave is a disturbance that travels through a medium in a periodic fashion, carrying energy without transporting matter. Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed. The period of a wave is the time it takes to complete one cycle.read more >>
