Traveling Wave Relationship

行波关系

A single frequency traveling wave will take the form of a sine wave. A snapshot of the wave in space at an instant of time can be used to show the relationship of the wave properties frequency, wavelength and propagation velocity.

The motion relationship "distance = velocity x time" is the key to the basic wave relationship. With the wavelength as distance, this relationship becomes λ = vT. Then using f=1/T gives the standard wave relationship

运动关系“距离=速度×时间”是基本波关系的关键。将波长作为距离，这一关系变为λ = vT。然后利用f=1/T得到标准的波关系。

This is a general wave relationship which applies to sound and light waves, other electromagnetic waves, and waves in mechanical media.

这是一种普遍的波动关系，适用于声波、光波、其他电磁波以及机械介质中的波。

一个单一频率的行波将呈现为正弦波的形式。在空间中某一时刻的波形快照可以用来展示波的性质——频率、波长和传播速度之间的关系。

波形计算

This is a general exploration calculation using the wave relationship.

这是一次使用波关系的通用探索计算。

Wave velocity = frequency x wavelength

波速等于频率乘以波长

Any of the numbers may be changed. When you have finished entering data, click the active text above for the quantity you wish to calculate. Unit conversions will be calculated as you enter data, but the three wave parameters will not be forced to be consistent until you click on the desired quantity.
Caution: for very large values, the first value for each quantity may not display all the digits. The values in scientific notation should be used.

任何数值都可以更改。当你完成数据输入后，点击上方的活动文本以选择你想要计算的量。单位转换会在输入数据时自动计算，但三个波参数在点击所需量之前不会被强制保持一致。注意：对于非常大的数值，每个量的第一个值可能无法显示所有数字。应使用科学记数法中的数值。
